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"

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.

some suggest kernel 6.7 will fix the issue but not sure about that.

You'll have to try it out when we release 6.7
