<span class="quote">> System Environment:
> --------------------------
> OS: Ubuntu 14.04.1 (kernel 3.13.0-45-generic)
> CPU: Intel Xeon E3-1285 V2 (IB)
> Mesa: 10.4.0-devel (git-514fd1c55e617bb325979cbee4a89f0727c3b567)
> VMware Workstation: 11.0.0 build-2281883
> VMware Player: 7.0.0 build-2281883
> VMware tools: 9.0.0 build-1541296

> After mentioned commit, some piglit tests start fails in Windows 7 VM under
> VMware Workstation(or Player).
>
> How to reproduce:
> -------------------------
> 1) install Mesa with guilty commit.
> 2) run VMware Player Windows 7 VM.
> 3) run piglit tests:
> spec/ARB_framebuffer_object/fbo-drawbuffers-none gl_FragColor
> spec/ARB_framebuffer_object/fbo-drawbuffers-none glDrawPixels
> spec/!OpenGL 1.1/drawbuffer-modes
> spec/EXT_framebuffer_object/fbo-drawbuffers
>
> Also I'm added to fbo-drawbuffers-none test some code for saving FBO content
> with various COLOR_ATTACHMENTs into TGA texture. As result, in case with
> COLOR_ATTACHMENT0 all looks fine, but with other attachments I see glitches
> instead red square.

> I reverted this commit and glitches gone. This commit added some
> functionality for gen 7 graphics (Haswell), but also breaks tests on
> previous graphics gen - Ivy Bridge. Looks like an commit added error to
