This adds an install script that clears the GPU shader cache on package upgrades. Cached shaders from older Chromium versions can cause: - Video flickering (especially on NVIDIA with Wayland) - GPU process crashes - Rendering glitches - WebGL failures The script clears GPUCache and ShaderCache directories for all users during package upgrades, preventing these issues. Fixes video rendering issues after upgrades. See: https://issues.chromium.org/issues/469458278 See: basecamp/omarchy#3891
