Summary: Major redraw/flicker issues on rv350 after exiting
fullscreen app with compiz running
Product: Mesa
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/r300
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: oreaus@gmail.com
With default packages in ubuntu natty 11.04, there is a problem where running
and exiting a fullscreen application with compiz running causes major
redraw/refresh flickering issues. They go away after restarting compiz, but
start again reliably after exiting any fullscreen GL app. Here are the bisect
results:
2a95568f64a6641a49a2d4855272e9be2ac2db6d is the first bad commit
commit 2a95568f64a6641a49a2d4855272e9be2ac2db6d

i965: Avoid register coalescing away MATH workarounds on Ivybridge.
The MATH instruction cannot handle source modifiers, even on Gen7.
So, apply this workaround for Sandybridge on Ivybridge as well.

As a side note, the problem is actually worse in mesa current master, where it
does not require triggering, but instead is flickering right after X/compiz
start the first time. I plan to bisect between the problem commit here and
master next to find out what causes it to get worse.
