Graphical corruption

Sometimes when resuming from sleep, or when playing a fullscreen video, my screen will fill with white video blocks.

rebooting will fix the problem (until it appears again).

    
$ uname -r

Similar to this: https://i.bke.ro/selif/artifacts.mp4 and https://www.youtube.com/watch?v=7Xt2e9Lt2gg

and issue: https://gitlab.freedesktop.org/drm/amd/-/issues/2735

One solution is to add amdgpu.sg_display=0

sudo kernelstub -a "amdgpu.sg_display=0"
