I see this on my AGP 7600GT (256M); as well as stopping video going full
screen, it makes mythtv frontend with the opengl drawing engine
unbelievably slow and cpu hungry (presumably it falls back to software
3d rendering or something). Would this be caused by texture memory
fragmentation or something? (Does video and/or whatever mythtv does need
a large _contiguous_ chunk of it? Or does that not make sense - does
texture memory get virtualised by an mmu (gart?) or something?).

Sadly I've had to stop using compiz as a result.
