Maybe something with WINE or the game is trying to swap cursor buffers frequently and it's interacting with the cursor double buffering in xf86-video-amdgpu. We still can't do fast cursor updates for swapping cursor framebuffers because we'll hit page faults that can kill the driver due to the cursor framebuffer not being properly refcounted. The fix for this particular bug is still under review in DRM. I plan on removing the restriction I added in amdgpu DM after the fix has been merged. But for now, whenever the cursor swaps framebuffers we can't perform fast cursor updates so we're forced to wait for the previous flip to finish and the vblank event to be sent back to userspace. This can cause small jitters depending on how often the cursor is updating and when it updates during the vblank interval.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
