I don't even know if the via chips are capable enough to do
EXT_texture_rectangle, so this may not be something easily solved.

It's better now. Running desktop-effects crashes the X server (in F7).

Comment 5 Adam Jackson 2008-02-12 10:43:45 EST
Well, yeah.  That bug is filed elsewhere, so I'll not worry too much about it here.

via hardware really doesn't have npot textures, at least not in chrome8 and
below, so this isn't getting fixed, ever.
