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 *** Bug 14969 has been marked as a duplicate of this bug. *** Same bug in archlinux http://bugs.archlinux.org/task/9866 Similar glitches in opengl games with mesa 7.0.3rc2 and intel graphics driver. Created attachment 15574 [details] [review] Re-enable -ve rhw workaround for all i965 chips. 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. Here's some before and after screenshots just to show the problem: http://pc486.net/screenshot/mesa-7-0-g965-incorrect.png http://pc486.net/screenshot/mesa-7-0-g965-correct.png (In reply to comment #6) > I noticed the same corruption in git (mesa_7_0_branch) and decided to track it > down yesterday.

The -ve rhw workaround should be applied to 965, not IGD *** Bug 14794 has been marked as a duplicate of this bug. *** *** Bug 15351 has been marked as a duplicate of this bug. *** |
