--- Comment #10 from Mike Bendel <mike@exophase.com> ---
I have the same issue. For me amdgpu.dc=0 does not really fix it either. I have
a 3840x1600 monitor running at 75 Hz. This is the different behavior I noticed
when toggling the DC setting:
amdgpu.dc=0
Moving windows smooth most of the time but cursor frequently skips frames
amdgpu.dc=1
There is stutter/tearing in the movement of windows but the cursor is
completely smooth otherwise.
Running 4.16.2 kernel here with a Radeon Pro WX 7100.
