--- Comment #12 from Kenneth Graunke <kenneth at whitecape.org> ---
I ran TRex on my Lenovo X250 (Broadwell GT2) using xserver master and
xf86-video-modesetting with Glamor for acceleration, and I see the exact same
corruption we saw with SNA.

So I think that completely rules out SNA as the source of the problem.  It's
probably a Mesa bug of sorts...
