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).

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"

These issues are common and need to be fixed by either AMD, Intel, NVIDIA, or the mainboard vendor; depending on which component is causing the issue. If a kernel option helps, then that's what you'll have to do until they fix it upstream in the kernel or firmware.
