Description tempel.julian 2022-06-19 14:56:03 UTC 
SUMMARY
Firefox native Wayland WebRender window flickers upon resizing in a Plasma Wayland session with Nvidia.

STEPS TO REPRODUCE
1. Start Plasma Wayland session with proprietary Nvidia driver (GBM).
2. Run Firefox and make sure it starts with native Wayland backend and WebRender enabled
3. Resize the main or downloads window:

OBSERVED RESULT
It shows black flickering upon doing so.

EXPECTED RESULT
It shouldn't do that, it doesn't do that with Intel GPU.

There's some known sync problems with Nvidia proprietary driver. Kwin can't do anything about it.
