Created attachment 28949 [details] Xorg.0.log Bug description: When using pymol[1], the graphics get worse after a second not touching the program. picture: http://dev.gentooexperimental.org/~jlec/paste/pymol.png bad video: http://dev.gentooexperimental.org/~jlec/paste/screen.mpg This can be overcome with setting Option "Tiling" "false", so I think it is really related to Tiling. System environment: -- chipset: 945G -- system architecture: 32bit -- xf86-video-intel: 2.8.1, but it is the same since 2.7.9 -- xserver: 1.6.3.901, but the same in 1.6* at least. -- mesa: 7.5 -- libdrm: 2.4.12 -- kernel: 2.6.30-gentoo-r4, but also with 2.6.29* and latest git sources -- Linux distribution: gentoo -- Machine or mobo model: desktop -- Display connector: vga Reproducing steps: - Install pymol [1] - fetch 3cwg - wait a second Additional info: none [1] www.pymol.org

Could you retest with Mesa master as of: commit 7c8bed62e0165a0be3363f7abf81bf9e30341e00 Author: Eric Anholt <eric@anholt.net> Date: Fri Oct 30 15:33:11 2009 -0700 intel: Use GTT mapping when available for swrast. This improves piglit quick.tests runtime from 19:33 minutes to 6:06 on my GM45. It should also hide most of the A17 swizzling issues, though they'll still exist when swapping occurs (which is the kernel's problem either way).
It is solved with following revisions * Messages for package x11-libs/libdrm-9999: * GIT NEW clone --> * repository: git://anongit.freedesktop.org/git/mesa/drm * at the commit: b0b96636dbf93445dd532b09b21fa4fc5ce6bdc7 * branch: master * Messages for package media-libs/mesa-9999: * GIT NEW clone --> * repository: git://anongit.freedesktop.org/mesa/mesa * at the commit: 87d7c1aa15a944d64e43b217e18553256f9fb681 * branch: master
Will this be backported to the 7.6 branch?
It's kind of intrusive, so I don't plan to.
