Texturing in 32bpp mode randomly messes up. it seems to happen mostly with a blue texture on top of a yellow one. and it is fairly predictable where it will show up. I just put up some screenshots from Unreal Tournament at:

I'm using a G400 MAX, with DRI as of 12/15/00. kernel 2.4.0-test12. UT v.436. gcc 2.95.2
I'm experiencing the same trying various opengl apps. In 16bpp everything is ok, but in 32bpp blue channel of texture is messed, looks like other textures (used earlier, or vertical lines after a power-up).
I'm using G400 MAX 32MB, DRI from dec 26 CVS, kernel 2.4.0-test 11.
Main test program is the Haugyjobb demo by Astral:

This bug seems to exists from the time of 4.0.2 merge.
I guess I'll just add a "me too" on this one, with the following set up:

I noticed the blue textures in Open Universe...
look at the moon from the Earth and watch the Milky Way in the background.... nice and blue :)

Have you been able to reproduce this problem with a more
recent DRI build? There have been quite a few changes to
texture management in the MGA driver since February of 2001.
