Comment # 33 on bug 77677 from G. Richard Bellamy

I have this issue using both Software and Hardware decoding on XBMC.

It is MUCH worse when using VDPAU and glamor HW acceleration, but is present
with SW-only acceleration.

I have an AMD Sapphire Redeon HD7750 with an Intel i3 running 3.15.3 kernel and
a git build (via mesa-git on Arch) of Mesa, libgl and ati-dri.
