Now, when Blender is GPLed I want to show this tdfx driver bug:
1) download Blender (binary, source, anything) from http://www.blender.org
2) run it
3) press F12 (rendering)
Everything becomes rainbow-coloured. Interface is no longer gray, mad colors
are everywhere. Main window grid, fonts, everything is rainbow...
Problem appear only on current (CVS) driver. When I install tdfx_dri.so from
XFree86-4.2.0 - everything works well.
When rendering is started - new window in Blender opens. I think something can
be wrong with OpenGL states. However I tried to run 2 different OpenGL
applications at one time (glxgears and game) and nothing was bad. Problem
happens when application like Blender  opens new window.
 but it isn't Blender specific, I remember I've seen something like that
with gtkglarea applications
