Kyle Kearney and Jordi Gutiérrez Hermoso both report corrupted rendering
on i965 with mesa 7.0.3-rc2. The problem did not occur with rc1
(Debian's 7.0.2-4).

Kyle said:
"I am experiencing graphics corruption in several 3D games since installing the
mesa 7.0.3-rc2 updates. A screenshot is attached illustrating the effect as it is
rather difficult to describe. I have observed this in supertuxkart, planet penguin
racer, armagetron, and open arena, both with and without compiz running. Glxgears
does not report any anomolies. My graphics processor is an Intel GMA x3100 (965
chipset)."

At least open arena works on my GM965.

Hi,

I can confirm that the bug is present if I use the 7.0.3-rc2 version of
the mesa library; I use Debian testing and I have an i965 video card. If
I try to play Vegastrike or Armagetron, I can see exactly the same kind
of graphics corruption that is shown in the screenshot:

http://bugs.debian.org/cgi-
bin/bugreport.cgi?msg=5;filename=Mesaproblem.png;att=1;bug=470084

I have not tried other 3D games or apps, so I cannot say whether there
are other programs affected by this bug on my system.

Also for me, the 7.0.2-4 (as named by Debian) version of the library
produced no artefacts.

Kind regards,

Mario

I noticed the same corruption in git (mesa_7_0_branch) and decided to
track it down yesterday. The offending commit is
da476ff02dd357d9909a2df9891ee645f5f776a0. It appears a workaround that
was always on was changed to IGD chips only. It appears that my G965
requires this workaround, so here's a patch to include all i965 chips
when executing the workaround. Patch included.

Regarding the patch, should the -ve rhw workaround even need a test? The
DRI driver is for all 965 chips after all.

Thanks . I make a mistake in that commit. The -ve rhw workaround should
be applied to 965, not IGD
