Comment # 3 on bug 97610 from Michel Dänzer

I can reproduce the problem on Kaveri, but not on Tonga.

It does look like some kind of tiling parameter mismatch, but since
xf86-video-amdgpu doesn't deal with tiling parameters directly, it's more
likely that the problem is in Mesa or even lower in the stack. Reassigning to
Mesa for now.
