Title:
[amdgpu] Display microstutters (unless PSR is disabled)
Status in linux package in Ubuntu:
Confirmed
Bug description:
My laptop's display is usually smooth. And mostly smooth if I fling a
page in Firefox, but as the scroll slows down it stutters heavily.
Disabling PSR (amdgpu.dcdebugmask=0x10) seems to eliminate the
problem.
