Description Stefan Dösinger 2009-06-02 03:02:06 UTC 
In some 3D apps texture loads fail randomly. This can be seen in Extreme Tuxracer, alon with a number of other apps. Once a game triggered this problem, it also extends to the 2D desktop(no compiz enabled)

I did not notice this problem until today, so it might be a regression. I tried to find a good state in the mesa tree, but could not find any. It could be a regression in the kernel code. Due to bug 21851 I have to disable agp on this machine. The problems may be related.

I'll attach a screensot showning the problem. Notice the broken glyphs in the terminal window and the broken "km/h" text in the bottom right corner of the game. I noticed the bug when by chance the static background was broken, but I could not get a screenshot of this.

The file was too big it seems

Can you attach your xorg log?  What versions of the ddx, mesa, and the drm are you using?
Comment 3 Michel Dänzer 2009-06-04 02:29:00 UTC 
What does

glxinfo -l|grep GL_MAX_TEXTURE_SIZE

say?

I'm away from home right now. I'll check this when I am back and have access to that computer again

Have you had access to that computer again any time in the last two years? :)

Yes, I did, and I did some retesting of the r200 driver a few days ago(See bug 27069, where I complained about performance 2 years ago and still complain about performance today).

This specific problem seems to be gone. I can see no problems on the 2D Desktop, and tuxracer / etracer work just fine. I think the max texture size the driver reported was 2048 for normal textures and 256 for volume maps.

(The ultimate goal of warming up the r200 machine again was to get the Wine unit tests working, but there are too many issues and I think there are better ways to invest the time)
