Comment 31 for bug 194638

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.
