A lightweight Windows utility that strobes a draggable overlay window through rapid colour cycles to unstick dead or stuck pixels.
- Frameless, always-on-top overlay window
- Drag to reposition, grab the bottom-right corner to resize
- Lock in place — becomes fully click-through so you can work or game while it runs
- Strobe speed control (20 ms – 250 ms)
- System tray icon for quick access; left-click toggles strobing
Photosensitivity warning: the strobe effect flashes bright colours rapidly. Do not use if you are affected by flashing lights.
- Windows 10/11
- Python 3.11+ with PyQt6 (for running from source)
python -m venv .venv
.\.venv\Scripts\Activate.ps1
pip install -r requirements.txt
python main.pypip install pyinstaller
python make_icon.py # generates assets/icon.ico
pyinstaller PixelFixer.spec # outputs dist\PixelFixer.exe| Action | Result |
|---|---|
| Left-click tray icon | Toggle strobing on/off |
| Right-click tray icon | Full menu (speed, lock, show/hide, quit) |
| Drag overlay body | Move the window |
| Drag bottom-right corner | Resize the window |
| Right-click overlay | Quick menu (speed, lock, hide) |
| Lock in Place (tray menu) | Freezes position; overlay becomes click-through |
The overlay cycles through red, green, blue, yellow, cyan, magenta, white, and black at a configurable interval. Rapidly alternating high-contrast colours exercises stuck sub-pixels and can restore normal function over minutes to hours of use.
