Comment # 40
on bug 106175
from Michel Dänzer
For the DC guys: We've now confirmed that the problem is due to some bad interaction between page flips and HW cursor updates. (In reply to tempel.julian from comment #37) > I think software cursor would also be unusable even if it left pageflipping > on. It causes nasty issues like flickering cursor or other visual corruption. Yeah, that's why xf86-video-amdgpu disables DRI page flipping while there's an SW cursor, as I said in comment 31. Note that the modesetting driver doesn't do this, allowing users to run into those issues.

Patches or at least specific suggestions welcome, but I'm afraid it's tricky to describe all possible interactions concisely and clearly. DRI page flipping and TearFree are mostly separate things, but they use the same kernel page flipping mechanism, which is what matters for this issue.
