fix(ui): disable hardware acceleration to prevent black window#76
Merged
Conversation
…ompatible GPUs On machines with incompatible GPU drivers, broken ANGLE, or VM setups, Chromium's GPU compositor silently fails — resulting in a black window the user can resize but never see content in. Disable hardware acceleration unconditionally since this is a system-cleaner utility where software compositing is perfectly adequate. Also fix the ErrorBoundary to use hardcoded fallback colors instead of CSS variables, so error messages remain visible even when stylesheets fail to load.

What does this PR do?
Disables Chromium hardware acceleration unconditionally and fixes the ErrorBoundary to use hardcoded fallback colors instead of CSS variables.
Why?
Users report a persistent black window they can resize but never see content in. This is a well-known Electron issue on machines with incompatible GPU drivers, broken ANGLE backends, or VM setups — the GPU compositor silently fails and only the window's background color (
#09090b) shows. Since Kudu is a system-cleaner utility, software compositing has negligible visual trade-off. The ErrorBoundary fix ensures error messages are visible even when stylesheets fail to load (previously black-on-black).How to test
