Comment # 36 on bug 106175 from bmilreu@gmail.com

So, to help find the origin of the issue, there are a few options that get rid
of stutter when compositing:

1 - amdgpu.dc=0 - The old DC seems unaffected by the bug.
2 - SWcursor on - Unaffected by bug because it disables pageflipping
3 - Pageflipping off
