I have KDE plasma on my debian pc. When I watch a video on yt and want to go fullscreen, sometimes the screen goes black until I leave fullscreen. The temporary fix is to change the render at the compositor, but it isnt a permanent solution. I have 2 sceens, one upscaled at 1080p (1366768 native) @60 Hz and one at 1024768 @75Hz. Is there any solution for this?
