When browsing the web with Firefox under KDE Plasma 6.3.5 Wayland, sometimes when moving the mouse over elements or scrolling, the display (120 Hz 2.8K variant) will flicker (not just the browser window). It might also occur with other applications, I didn’t do much testing yet (it didn’t happen in games so far).

I’ve recorded a short clip where this occurs (sorry for the low quality):

This did not happen with my Core Ultra 125H mainboard. I have tried the suggestion from this Reddit comment (setting amdgpu.dcdebugmask=0x410) but to no avail (seems to be a slightly different issue).

Any idea what is going on here and a possible fix?

Did you found a solution? I can’t see your video, but I guess I have the same problem on arch and gnome.

Arch wiki mentions:
Wayland sometimes interferes with hardware video decoding. If video briefly flickers when you go fullscreen, you may need to set widget.wayland.opaque-region.enabled=false in about:config.

I did this and I think it became less. But sometimes it still happens.
