Barely started PC, opened palemoon, curse move only hang and then dozens of
graphical artifacts on screen like square patches of glitches. 

Nov  3 13:15:10 pop-os kernel: [  133.998883]
[drm:amdgpu_dm_commit_planes.constprop.0 [amdgpu]] *ERROR* Waiting for fences
timed out!
Nov  3 13:15:10 pop-os kernel: [  139.118912] [drm:amdgpu_job_timedout
[amdgpu]] *ERROR* ring gfx_0.0.0 timeout, signaled seq=11145, emitted seq=11148

Nov  3 13:15:10 pop-os kernel: [  139.118958] [drm] GPU recovery disabled.

Then sometime later I got ring gfx related crash with Witcher 3 which didn't
happen before:
