Created attachment 53583 [details] ET:Quake Wars Intel(R) Pentium(R) CPU G620 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Desktop x86/MMX/SSE2 OpenGL version string: 2.1 Mesa 7.12-devel ET:Quake Wars, Unreal tournament 2004, Heroes of Newerth, shows arttifacts with current git of mesaa and intel drivers. But open source games like openarena, nexuiz, lightmark wirks fine, with out artifacts.
Xun, can you reproduce this issue with ETQW on our Sandy Bridge desktop (Core i5)?
Created attachment 53590 [details] Heroes of Newerth
Created attachment 53591 [details] UT 2004
with mesa-git 2011.09.27 all works fine, but mesa-git 2011.10.17 and newer shows artifacts.
At least the Heroes of Newerth and UT 2004 looks like it might be related to bug 41451. If checking out e0304180c32227342dbb67b707bfae446543bb48 or e0304180c32227342dbb67b707bfae446543bb48 (last good respectively bad commit regarding bug mentioned above), it's also worth doing "git cherry-pick 3cc0a7be23ab603ed40d602595f673a44e079885" to avoid possible hard lockups. ET:Quake wars remind me of some shader going out of bounds. Does starting it from console as: MESA_EXTENSION_OVERRIDE=-GL_NV_vertex_program ./etquakewars_binary have an effect?
MESA_EXTENSION_OVERRIDE=-GL_NV_vertex_program has no effect e0304180c32227342dbb67b707bfae446543bb48 fix UT2004 and HoN, but ETQW show artifacts
This is odd, but I'm not able to reproduce the artifacts on the Heroes of Newerth title screen using my Sandybridge(core i5). Even tried the 32-bit version. xf86-video-intel: git at 4a27dd287cdb85d80ceaf6b54e7de0c17e01c00d mesa: git at 75cc24c876059d6eb183e07ed802f997fb416864 kernel: 3.1.1-2.fc16.x86_64 (from fedora 16) Iaroslav, would you please post actual git revisions and kernel version you see this bug with?
I don't know if this is in any way related, but bug #42506 also only happens on a G620/G630 system and NOT on a i5 system. Also the artifacts in the UT 2004 screenshots look a little bit like the random artifacts I have in VAAPI accelerated videos: http://www.youtube.com/watch?v=ciITY_yER60 see bug #42506 for details.
HON intro screen is definitely fixed by the fix in #41451.

Iaroslav: For manageability (unless a developer corrects me on this), file a new bug for the gpu hang and let this one be about the visual artifacts. Also consider learning how to do git bisects in order to find the commit that caused the change in behavior, that will increase the chances of finding the bugs.
visual artifacts in UT2004 and Heroes of Newerth fixed, but ET:Quake Wars segfault every time with lates mesa, and i don't know they fixed or not. I can provide codedump file, and INTEL_DEBUG=all log if needed.
ETQW still have artifacts with current master branch on git. FYI compiling Mesa with --enable-debug, and assert is triggered when starting a game: brw_eu_emit.c:1671: brw_math2: Assertion `!src1.negate' failed This might indicate the the cause of the artifacts.
I see that corruption on ivb, which doesn't have the math operand modifier restrictions. Also, the corruption looks like vertex position getting trashed, as opposed to just fragment shader math issues (which is where that bad POW is).
Screenshot issue is now fixed: commit 0334e8dc25d09e3254e61d5d122b4fd7bfbd627a Author: Eric Anholt <eric@anholt.net> Date: Fri Sep 21 07:50:05 2012 +0200 i965: Remove broken non-interleaved-to-interleaved upload code. This failed when all the uploads to occur were uniform-type vertex data (lik glColor4f being active across a DrawArrays), because it would upload 1 eleme instead of 1 element per vertex. There was no citation for how this code helped any particular application, and it breaks ETQW, so just remove it.
