## 🔴 HIGH PRIORITY BUGS
### GUI-1: PopOutWindow Uses Old Color Scheme
**Severity:** HIGH
**Location:** gui_main_pro.py:797-856
**Category:** Critical UI Bug
**Issue:**
The `PopOutWindow` class doesn't use the modern `NeoCyberColors` scheme. It has hardcoded old gradient colors from a previous design iteration.
**Current Code:**
```python
# Line 823-824: OUTDATED COLORS
close_btn.setStyleSheet("""
QPushButton {
background: qlineargradient(x1:0, y1:0, x2:1, y2:1,
stop:0 #667eea, stop:1 #764ba2); # OLD GRADIENT!
...
}
""")
# Line 844-846: DIFFERENT BACKGROUND
self.setStyleSheet("""
QWidget {
background: qlineargradient(x1:0, y1:0, x2:1, y2:1,
stop:0 #0f0c29, stop:0.5 #302b63, stop:1 #24243e);
...
}
""")
```
**Impact:**
- Visual inconsistency - pop-out windows look completely different
- Breaks the "Neo Cyber" theme
- Confusing UX - users think it's a different app
- Old purple gradient clashes with new teal/blue scheme
**Fix Required:**
```python
class PopOutWindow(QWidget):
def __init__(self, title, content, parent=None):
super().__init__(parent)
# ... existing code ...
# Use modern NeoCyberColors
close_btn = AnimatedButton("Close", gradient=(COLORS.ERROR, "#f87171"))
close_btn.clicked.connect(self.close)
def apply_dark_mode(self):
self.setStyleSheet(f"""
QWidget {{
background: qlineargradient(x1:0, y1:0, x2:1, y2:1,
stop:0 {COLORS.BG_DEEP},
stop:0.5 #0f0f14,
stop:1 {COLORS.BG_DEEP});
color: {COLORS.TEXT_PRIMARY};
font-family: 'Inter', sans-serif;
}}
QTextEdit {{
background: {COLORS.BG_CARD};
color: {COLORS.TEXT_PRIMARY};
border: 1.5px solid {COLORS.BORDER_DEFAULT};
border-radius: 12px;
padding: 16px;
font-family: 'Fira Code', 'Consolas', monospace;
}}
""")
```
---
### GUI-14: Log Viewer Redraws Entire Text Every Update
**Severity:** HIGH
**Location:** gui_main_pro.py:1719-1726
**Category:** Performance Bug
**Issue:**
The log viewer clears and rebuilds the entire text widget every second, even for small updates.
**Current Code:**
```python
def update_logs(self):
# ... filter logic ...
self.log_view.clear() # ❌ CLEARS EVERYTHING!
for line in filtered:
cursor = self.log_view.textCursor()
cursor.movePosition(QTextCursor.MoveOperation.End)
self.log_view.setTextCursor(cursor)
self.log_view.setTextColor(self._log_color_for_line(line))
self.log_view.insertPlainText(line + "\n") # ❌ REBUILDS FROM SCRATCH
```
**Impact:**
- **Severe performance degradation** with logs >1000 lines
- GUI freezes when log file is 10MB+
- High CPU usage (30%+ on modest hardware)
- Scrolling resets to bottom on every update
- User can't read logs while they update
**Fix Required:**
```python
def update_logs(self):
if not self.log_file or not self.log_file.exists():
return
try:
# Track last read position
if not hasattr(self, '_log_last_pos'):
self._log_last_pos = 0
# Only read new lines since last update
with open(self.log_file, 'r') as f:
f.seek(self._log_last_pos)
new_lines = f.readlines()
self._log_last_pos = f.tell()
# Apply filters
level = self.level.currentText()
search = self.search.text().lower()
for line in new_lines:
if level != "All" and level not in line:
continue
if search and search not in line.lower():
continue
# Append only new filtered lines
cursor = self.log_view.textCursor()
cursor.movePosition(QTextCursor.MoveOperation.End)
self.log_view.setTextCursor(cursor)
self.log_view.setTextColor(self._log_color_for_line(line))
self.log_view.insertPlainText(line)
# Update summary
if hasattr(self, "log_summary_label"):
total_lines = self.log_view.document().lineCount()
self.log_summary_label.setText(f"Showing {total_lines} log lines")
except Exception as e:
logger.debug(f"Error updating logs: {e}")
```
---
## 🟠 MEDIUM PRIORITY BUGS
### GUI-2: Toast Notifications Position Calculation Bug
**Severity:** MEDIUM
**Location:** gui_main_pro.py:982-998
**Issue:**
Toast notifications calculate Y position based on list length, but when toasts are dismissed, remaining toasts don't reposition.
**Current Code:**
```python
def show_toast(self, message: str, toast_type: str = "info"):
toast = ToastNotification(message, toast_type, self)
toast.setGeometry(0, 0, 420, 80)
toast.move(self.width() - toast.width() - 20,
self.height() - toast.height() - 20 -
(len(self._toast_notifications) * (toast.height() + 10))) # ❌ WRONG
toast.show()
self._toast_notifications.append(toast)
# Timer to auto-remove after 4 seconds
QTimer.singleShot(4000, lambda: toast.close() and
self._toast_notifications.remove(toast)) # ❌ DOESN'T REPOSITION OTHERS
```
**Impact:**
- Toasts overlap or have large gaps
- Visual glitch when toast disappears
- Poor UX
**Fix:**
```python
def show_toast(self, message: str, toast_type: str = "info"):
toast = ToastNotification(message, toast_type, self)
toast.setGeometry(0, 0, 420, 80)
self._toast_notifications.append(toast)
self._reposition_toasts() # Reposition all toasts
toast.show()
# Auto-remove and reposition
def remove_toast():
if toast in self._toast_notifications:
self._toast_notifications.remove(toast)
toast.close()
self._reposition_toasts() # Reposition remaining toasts
QTimer.singleShot(4000, remove_toast)
def _reposition_toasts(self):
"""Reposition all visible toasts"""
y_offset = self.height() - 20
for toast in reversed(self._toast_notifications):
y_offset -= toast.height()
toast.move(self.width() - toast.width() - 20, y_offset)
y_offset -= 10 # Gap between toasts
```

### GUI-3: Gradient Animation Timer Never Stops
**Severity:** MEDIUM
**Location:** gui_main_pro.py:373-375
**Issue:**
`AnimatedButton` starts gradient animation timer but never stops it, even when button is hidden or destroyed.
**Code:**
```python
def __init__(self, ...):
# ...
self._gradient_timer = QTimer(self)
self._gradient_timer.timeout.connect(self._advance_gradient)
self._gradient_timer.start(60) # ❌ NEVER STOPPED!
```
**Impact:**
- Wastes CPU (timer fires every 60ms forever)
- Battery drain on laptops
- Unnecessary repaints
- Memory leak if buttons not properly cleaned up
**Fix:**
```python
def hideEvent(self, event):
"""Stop animation when hidden"""
super().hideEvent(event)
if hasattr(self, '_gradient_timer'):
self._gradient_timer.stop()
def showEvent(self, event):
"""Resume animation when shown"""
super().showEvent(event)
if hasattr(self, '_gradient_timer'):
self._gradient_timer.start(60)
def __del__(self):
"""Clean up timer on destruction"""
if hasattr(self, '_gradient_timer'):
self._gradient_timer.stop()
self._gradient_timer.deleteLater()
```
---
### GUI-4: Header Gradient Timer Leaks
**Severity:** MEDIUM
**Location:** gui_main_pro.py:941-955
**Issue:**
Similar to GUI-3, header gradient timer runs continuously without checking if window is visible.
**Fix:**
```python
def hideEvent(self, event):
"""Stop timers when window hidden"""
super().hideEvent(event)
if hasattr(self, 'timer'):
self.timer.stop()
if hasattr(self, '_header_timer'):
self._header_timer.stop()
def showEvent(self, event):
"""Resume timers when window shown"""
super().showEvent(event)
if hasattr(self, 'timer'):
self.timer.start(1000)
if hasattr(self, '_header_timer'):
self._header_timer.start(90)
```
---
### GUI-5: Pop-out Window Styling Inconsistency
**Severity:** MEDIUM
**Location:** gui_main_pro.py:842-856
**Issue:**
`PopOutWindow.apply_dark_mode()` uses completely different gradient than main application.
**Impact:**
- Visual inconsistency
- Confusing user experience
- Looks like different applications
**Fix:** Use same `NeoCyberColors` and gradients as main window (see GUI-1 fix).
---
### GUI-11: No Loading Indicator
**Severity:** MEDIUM
**Location:** N/A (missing feature)
**Issue:**
No visual feedback when:
- Loading large files (>100KB)
- Starting backend server
- Waiting for LLM response
- Loading memory explorer
**Impact:**
- App appears frozen
- Users don't know if action is working
- Poor UX, users force-quit thinking it crashed
**Fix:**
```python
class LoadingOverlay(QWidget):
"""Modern loading spinner overlay"""
def __init__(self, parent=None):
super().__init__(parent)
self.setAttribute(Qt.WidgetAttribute.WA_TransparentForMouseEvents, False)
self.setStyleSheet(f"""
background-color: rgba(0, 0, 0, 0.7);
""")
layout = QVBoxLayout()
layout.setAlignment(Qt.AlignmentFlag.AlignCenter)
spinner = QLabel("⏳")
spinner.setFont(QFont("Segoe UI Emoji", 48))
spinner.setStyleSheet(f"color: {COLORS.PRIMARY};")
spinner.setAlignment(Qt.AlignmentFlag.AlignCenter)
text = QLabel("Loading...")
text.setFont(QFont("Inter", 14, QFont.Weight.DemiBold))
text.setStyleSheet(f"color: {COLORS.TEXT_PRIMARY};")
text.setAlignment(Qt.AlignmentFlag.AlignCenter)
layout.addWidget(spinner)
layout.addWidget(text)
self.setLayout(layout)
def show_loading(self):
self.setGeometry(self.parent().rect())
self.show()
self.raise_()
# Usage:
def on_file_click(self, item, column):
try:
file_path = item.data(0, Qt.ItemDataRole.UserRole)
if file_path and Path(file_path).is_file():
path = Path(file_path)
if path.stat().st_size > 100_000: # Show loader for large files
loader = LoadingOverlay(self)
loader.show_loading()
QApplication.processEvents() # Update UI
try:
content = path.read_text(encoding='utf-8')
self.preview.setPlainText(content)
finally:
loader.close()
else:
content = path.read_text(encoding='utf-8')
self.preview.setPlainText(content)
except Exception as e:
logger.error(f"Error previewing file: {e}")
```
---
### GUI-15: Memory Explorer Full Refresh on Timer
**Severity:** MEDIUM
**Location:** gui_main_pro.py:1738-1769
**Issue:**
`update_memory_explorer()` called every second, rebuilds entire tree even if file hasn't changed.
**Current Has Fix But Called Too Often:**
```python
# Line 1755-1756: Already has mtime check!
if not force and self._memory_last_mtime and stat.st_mtime <= self._memory_last_mtime:
return # Good!
# But it's called every 1 second from update_logs (line 1731)
```
**Impact:**
- Unnecessary CPU usage
- Tree flickers if expanded
- Resets scroll position
**Fix:**
Move to separate timer with longer interval:
```python
def __init__(self):
# ... existing code ...
# Separate timer for memory explorer (slower refresh)
self.memory_timer = QTimer(self)
self.memory_timer.timeout.connect(lambda: self.update_memory_explorer(force=False))
self.memory_timer.start(5000) # Every 5 seconds instead of every second
```
---
### GUI-16: File Tree Not Virtualized
**Severity:** MEDIUM
**Location:** gui_main_pro.py:1518-1536
**Issue:**
Loads entire directory tree into memory at once, recursively adding all items.
**Impact:**
- Slow with large projects (1000+ files)
- High memory usage
- GUI freezes during load
- O(n) complexity for every directory
**Fix:**
Implement lazy loading:
```python
def _add_tree_items(self, parent, path, lazy=True):
"""Add tree items with optional lazy loading"""
try:
if lazy and not parent.isExpanded():
# Add placeholder for lazy load
placeholder = QTreeWidgetItem(["Loading..."])
parent.addChild(placeholder)
parent.setData(0, Qt.ItemDataRole.UserRole + 1, str(path)) # Store path
return
for p in sorted(path.iterdir(), key=lambda x: (not x.is_dir(), x.name)):
if p.name.startswith('.') or p.name in ['node_modules', '__pycache__']:
continue
item = QTreeWidgetItem([p.name])
item.setData(0, Qt.ItemDataRole.UserRole, str(p))
parent.addChild(item)
if p.is_dir():
self._add_tree_items(item, p, lazy=True) # Lazy for subdirectories
except Exception as e:
logger.warning(f"Error adding tree items for {path}: {e}")
def on_tree_item_expanded(self, item):
"""Load children when item expanded (lazy loading)"""
if item.childCount() == 1 and item.child(0).text(0) == "Loading...":
# Remove placeholder
item.removeChild(item.child(0))
# Load actual children
path_str = item.data(0, Qt.ItemDataRole.UserRole + 1)
if path_str:
path = Path(path_str)
self._add_tree_items(item, path, lazy=False)
# Connect in __init__:
self.tree.itemExpanded.connect(self.on_tree_item_expanded)
```
---
### GUI-18: No Backend Health Monitoring
**Severity:** MEDIUM
**Location:** N/A (missing feature)
**Issue:**
GUI doesn't detect if backend process crashes. Status stays "🟢 Running" even if process died.
**Impact:**
- Misleading status indicator
- Users don't know backend crashed
- Waste time troubleshooting wrong thing
**Fix:**
```python
def __init__(self):
# ... existing code ...
# Health check timer
self.health_timer = QTimer(self)
self.health_timer.timeout.connect(self._check_backend_health)
self.health_timer.start(5000) # Check every 5 seconds
def _check_backend_health(self):
"""Monitor backend process health"""
if self.process is not None:
if self.process.poll() is not None:
# Process has terminated
logger.error("Backend process crashed!")
self.connection_status.set_status("error", "🔴 Backend crashed")
self.start_btn.setText("▶ Start Server")
self.process = None
# Show error toast
self.show_toast(
"Backend server crashed! Check logs for details.",
"error"
)
```

## 🟡 LOW PRIORITY BUGS
### GUI-6: Fixed Window Size Prevents Responsive Design
**Severity:** LOW
**Location:** gui_main_pro.py:866-867
**Issue:**
Window always resizes to 1720x1080, too large for smaller screens (1366x768 laptops).
**Fix:**
```python
# Get screen size
screen = QApplication.primaryScreen().geometry()
width = min(1720, int(screen.width() * 0.9))
height = min(1080, int(screen.height() * 0.9))
self.resize(width, height)
# Center on screen
self.move(
(screen.width() - width) // 2,
(screen.height() - height) // 2
)
```
---
### GUI-7: No Window State Persistence
**Severity:** LOW
**Location:** gui_main_pro.py:957-977
**Issue:**
Window size and position not saved between sessions.
**Fix:**
```python
def _load_session(self):
"""Load saved session settings including window geometry"""
if self.session_file.exists():
try:
settings = json.loads(self.session_file.read_text())
self._last_directory = settings.get('last_directory')
self._last_provider = settings.get('last_provider', 'grok')
# Restore window geometry
geometry = settings.get('window_geometry')
if geometry:
self.setGeometry(
geometry['x'], geometry['y'],
geometry['width'], geometry['height']
)
except Exception as e:
logger.debug(f"Error loading session: {e}")
def _save_session(self):
"""Save session including window geometry"""
try:
geometry = self.geometry()
settings = {
'last_directory': self.path_edit.text(),
'last_provider': self.provider.currentText(),
'window_geometry': {
'x': geometry.x(),
'y': geometry.y(),
'width': geometry.width(),
'height': geometry.height()
}
}
self.session_file.write_text(json.dumps(settings, indent=2))
except Exception as e:
logger.debug(f"Error saving session: {e}")
```
---
### GUI-8: Splitter Sizes Hardcoded
**Severity:** LOW
**Location:** gui_main_pro.py:1241
**Issue:**
File explorer splitter hardcoded to [420, 1080], doesn't scale with window size.
**Fix:**
```python
# Use proportional sizes
total_width = self.width() - 100 # Account for margins
split.setSizes([int(total_width * 0.3), int(total_width * 0.7)])
# Save/restore splitter state
def _load_session(self):
# ... existing code ...
splitter_sizes = settings.get('splitter_sizes')
if splitter_sizes and hasattr(self, 'tree'):
split = self.tree.parent().parent() # Get splitter widget
if isinstance(split, QSplitter):
split.setSizes(splitter_sizes)
def _save_session(self):
# ... existing code ...
if hasattr(self, 'tree'):
split = self.tree.parent().parent()
if isinstance(split, QSplitter):
settings['splitter_sizes'] = split.sizes()
```
---
### GUI-10: Syntax Highlighter Not Applied to Pop-out Windows
**Severity:** LOW
**Location:** gui_main_pro.py:813-814
**Issue:**
Pop-out windows only highlight `.py` files by checking title extension. Doesn't handle other languages.
**Fix:**
```python
def __init__(self, title, content, parent=None):
# ... existing code ...
# Detect language from extension
ext = Path(title).suffix.lower()
if ext == '.py':
PythonHighlighter(self.text_edit.document())
elif ext in ['.js', '.jsx', '.ts', '.tsx']:
# Add JavaScript highlighter
JavaScriptHighlighter(self.text_edit.document())
elif ext in ['.html', '.htm']:
# Add HTML highlighter
HTMLHighlighter(self.text_edit.document())
# etc.
```
---
### GUI-12: Error Messages Use QMessageBox
**Severity:** LOW
**Location:** Multiple locations
**Issue:**
Standard Qt message boxes don't match the modern theme.
**Fix:**
Create custom modal dialog:
```python
class ModernDialog(QDialog):
"""Modern dialog matching app theme"""
def __init__(self, title, message, dialog_type="info", parent=None):
super().__init__(parent)
self.setWindowTitle(title)
self.setModal(True)
self.setMinimumWidth(400)
layout = QVBoxLayout()
layout.setContentsMargins(32, 32, 32, 32)
layout.setSpacing(20)
# Icon + Message
icon_map = {
"info": "ℹ️",
"warning": "⚠️",
"error": "❌",
"success": "✅"
}
msg_label = QLabel(f"{icon_map.get(dialog_type, 'ℹ️')} {message}")
msg_label.setWordWrap(True)
msg_label.setStyleSheet(f"""
color: {COLORS.TEXT_PRIMARY};
font-size: 14px;
font-weight: 500;
font-family: 'Inter';
""")
layout.addWidget(msg_label)
# OK button
ok_btn = AnimatedButton("OK", gradient=(COLORS.PRIMARY, COLORS.SECONDARY))
ok_btn.clicked.connect(self.accept)
layout.addWidget(ok_btn)
self.setLayout(layout)
self.setStyleSheet(f"background: {COLORS.BG_CARD};")
# Usage:
# Instead of: QMessageBox.warning(self, "Error", "Something went wrong")
# Use: ModernDialog("Error", "Something went wrong", "error", self).exec()
```
---
### GUI-17: Pending Edit Check Polling Too Aggressive
**Severity:** LOW
**Location:** gui_main_pro.py:1734
**Issue:**
Checks for pending edits every 1 second via file I/O.
**Fix:**
Use file system watcher:
```python
from PyQt6.QtCore import QFileSystemWatcher
def __init__(self):
# ... existing code ...
self.file_watcher = QFileSystemWatcher()
self.file_watcher.fileChanged.connect(self._on_pending_edit_changed)
def start_server(self):
# ... existing code ...
# Watch for pending edit file
pending_file = Path(dir_path) / ".fgd_pending_edit.json"
if not self.file_watcher.files():
self.file_watcher.addPath(str(pending_file.parent))
def _on_pending_edit_changed(self, path):
"""Called when pending edit file changes"""
self.check_pending_edits()
```
---
### GUI-19: Provider Change Doesn't Update Running Server
**Severity:** LOW
**Location:** gui_main_pro.py:1084-1086
**Issue:**
Changing provider dropdown while server running has no effect, confusing UX.
**Fix:**
```python
def start_server(self):
# ... existing code ...
# Disable provider dropdown when server running
self.provider.setEnabled(False)
def toggle_server(self):
if self.process and self.process.poll() is None:
# ... stop server ...
self.provider.setEnabled(True) # Re-enable provider selector
else:
self.start_server()
```
---
### GUI-20: No Keyboard Shortcuts
**Severity:** MEDIUM
**Location:** N/A (missing feature)
**Issue:**
No keyboard shortcuts for common actions.
**Fix:**
```python
def __init__(self):
# ... existing code ...
# Add keyboard shortcuts
QShortcut(QKeySequence("Ctrl+R"), self, self._refresh_all)
QShortcut(QKeySequence("Ctrl+S"), self, self.toggle_server)
QShortcut(QKeySequence("Ctrl+L"), self, lambda: self.tabs.setCurrentIndex(2)) # Logs
QShortcut(QKeySequence("Ctrl+M"), self, lambda: self.tabs.setCurrentIndex(3)) # Memory
QShortcut(QKeySequence("Ctrl+Q"), self, self.close)
QShortcut(QKeySequence("F5"), self, self._refresh_all)
def _refresh_all(self):
"""Refresh all views"""
if hasattr(self, 'path_edit') and self.path_edit.text():
self.load_file_tree(self.path_edit.text())
self.update_logs()
self.update_memory_explorer(force=True)
self.show_toast("Refreshed all views", "success")
```

### GUI-23: Pop-out Windows Not Tracked Properly
**Severity:** LOW
**Location:** gui_main_pro.py:996, 1488-1506
**Issue:**
`pop_out_windows` list appends but never removes closed windows, causing memory leak.
**Fix:**
```python
def pop_out_preview(self):
"""Pop out preview window"""
content = self.preview.toPlainText()
if content:
window = PopOutWindow("Code Preview", content, self)
window.destroyed.connect(lambda: self._remove_pop_out(window))
window.show()
self.pop_out_windows.append(window)
def _remove_pop_out(self, window):
"""Remove closed window from list"""
if window in self.pop_out_windows:
self.pop_out_windows.remove(window)
```
---
### GUI-24: Pop-out Windows Have No Parent Relationship
**Severity:** LOW
**Location:** gui_main_pro.py:1488, 1496, 1504
**Issue:**
Pop-out windows created as `QWidget`, should be `QDialog` to stay on top of main window.
**Fix:**
```python
class PopOutWindow(QDialog): # Changed from QWidget
def __init__(self, title, content, parent=None):
super().__init__(parent)
self.setWindowTitle(title)
self.setWindowFlags(
Qt.WindowType.Dialog |
Qt.WindowType.WindowCloseButtonHint |
Qt.WindowType.WindowMaximizeButtonHint
)
# ... rest of code ...
```
