Comment 5 Alex Deucher 2014-06-09 01:21:39 UTC 
This isn't a driver bug.  It's a weston bug.  Weston assumes all hardware cursors are 64x64 pixels, but newer radeon hardware only supports 128x128 pixel cursors. Weston should be updated to query the kernel kms driver and see what size cursors it supports.  See this patch I wrote for xf86-video-modesetting:

Thanks for answering!

I've uploaded a patch to weston bugtracker, so I think the bug can be closed here as invalid.
