Textures corruption

Having played both the original game and the Winter Assault expansion without problems using the i965 driver, I gave the demo of Soulstorm a try. It works fine here, but if I disable S3TC support, I get the same corruption as your screenshots.

Could you try either:

- Installing the libtxc_dxtn library (should be available somewhere for your distro, otherwise get it here: http://homepage.hispeed.ch/rscheidegger/dri_experimental/s3tc_index.html )

- Setting "Enable S3TC texture compression" to "Yes" in driconf. (or just force_s3tc_enable=true )

Installing that library has solved the textures and bitmaps corruption problem, thanks! However, the GPU still hangs as mentionned in dmesg.

I tried getting a dump, but I couldn't find intel_reg_dumper in intel-gpu-tools-1.0.2, I only found intel_gpu_dump. However, it doesn't work as a user, and it hangs the machine as root, forcing me to reboot (I tried intel_gpu_dump > gpu_dump as root, and the machine becomes completely unresponsive).

I couldn't find driconf, and I don't know where to put force_s3tc_enable=true; however, since installing libtxc_dxtn worked, I guess it isn't mandatory?

Thanks for your help!

The GPU reset function will probably mean that you won't get a meaningful dump with that kernel anyway. The best way is to retry with git master of Mesa, and the latest rc of 2.6.34. 

If the hang is still there, grab a dump with intel_error_decode.

(At least this is what I usually do.)

No, shouldn't be necessary if the lib is used.

Thanks for your suggestions, installing the latest git of Mesa and/or 2.6.34-rc6 solved the GPU hang problem.

Now the game plays, but some models are distorted: the polygons extend out of the characters(?).

Furthermore, about 1 pixel is chopped of the letters (see screenshot).

Thanks again anyway!

These I can't reproduce, sorry.

I guess either the demo isn't enough to reproduce this, or it's a problem specific to your hardware (I use a X4500HD).

Hi,

Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org.

To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default).

Sorry about the noise!
