Works fine for me with Mesa master or 36edcebb9012f530a9288956a7fd3b21f9bb8aed on GM45.

Run walktest-1.2 and move around with arrows, you will get what I showed on screenshot. If you try walktest-1.4 or walktest-1.9 the window will be black, showing from time to time very dark artefacts when you push arrow buttons. walktest-1.2 is from debian package of crystalspace 1.2.1 walktest-1.4 and walktest-1.9 are custom compiled from sources (cs 1.4 and 1.9-dev), they don't overlap. my master is d3912e301fd707738b0952cd11e19f34b87765b8 Tested with debian packaged mesa 7.5 bug still present. Configuration is as follow 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) Xorg 1.6.1 mesa 7.5 xf86-video-intel 2.7.1 libdrm 2.4.11 linux 2.6.30 (kms enabled) (In reply to comment #2) > (In reply to comment #1) > > Works fine for me with Mesa master or 36edcebb9012f530a9288956a7fd3b21f9bb8aed > > on GM45. > > > > It does not on GM965.

I was not able to reproduce this error. The date on the SHA1 you quote is from May, which is quite old at this point. Are you still able to reproduce this bug?

This is probably some kind of specific case that I hit, I tried removing libtxc-dxtn for S3TC but it did not help. I am going to attach log file from walktest. Created attachment 29165 [details]
Walktest log from Crystalspace 1.2.1-2
Attaching /usr/bin/walktest > walktest.txt 2> walktest.txt
Crystalspace from Debian (sid)
ii crystalspace 1.2.1-2
Problem still exist
I could not reproduce it anymore either, so I think it was fixed meanwhile. But if it still happens with latest Intel graphics stack, please reopen the bug so we could investigate it further. Cannot reproduce it. Seems to be fixed. Reopen if needed. |

Created attachment 25208 [details] Screenshot showing artefacts. Hi, I installed package crystalspace and on other systems it works fine, while on GM965 with latest mesa master branch (28-04-09) walktest produce 3D rendering with artifacts as on attached screenshot.
