<pre>This is pretty serious. Just moving the mouse cursor around while something
slightly GPU-heavy is running at 60hz can produce frame-skipping.
I switched the display core off with amdgpu.dc=0 and everything got
significantly smoother and chromium doesn't chug on heavy pages any more.
I'm using 4.19.x. I haven't tried the drm-next-4.21-wip tree yet.</pre>
