--- Comment #20 from Rodrigo Vivi <rodrigo.vivi at gmail.com> ---
The GT3 issue is strange because it isn't a gpu hang. Using ITP everything
looks correct on CSs. And the behaviour for user is not the same. QA is facing
blank screens in some cases I face in other cases.
Sometimes my KDE environment starts showing but then I just get the background
and the mouse. Other times it is just frozen.

The bisect here on this bug is invalid. I get same behaviour with the known
best commit. And same result on rendercheck. I'm not sure either if the
rendercheck test is the more appropriated one to catch this bug, but since
thats the one here on this bug I'm going to paste my result here and the
Xorg.0.log with full ddx debug.

$ xinit /usr/bin/rendercheck -t blend,composite -f a8r8g8b8
