Hi,
I've found some texturing modes course corruption and lockups on my

With quake3 I get corruption, and often lockup when starting a
match/map. Q3DM0 locks up 9 out of 10 times. Q3DM17 works 10 out of 10
times.
This is most likely r420 specific.
Q3DM0 would seem to use multi texturing more often than Q3DM17, so you might
want to try progs/demos/multiarb .
I coulden't reproduce the corruption with multiarb.
I do however think I've found a partial fix, it looks ike someone
commented out a break by mistake. correcting this fixed the textures in
bzflag (the menu is still corrupted).
patch attached.

[r300] texturing mode issue with r420 (X800 XT)
Hi, I've found some texturing modes course corruption and lockups on my hardware. With quake3 I get corruption, and often lockup when starting a match/map. Q3DM0 locks up 9 out of 10 times. Q3DM17 works 10 out of 10 times. With bzflag I get corruption the instent I select the affected modes. The affected texture modes are: NEAREST_MIPMAP_LINEAR LINEAR_MIPMAP_LINEAR LINEAR_MIPMAP_NEAREST setup: I uning the latest CVS versions of DRM and Mesa. Xorg is about 2 weeks old. Can someone confirm if this is a general problem or just on my setup? And does anyone have any idea as to what the caues could be?
