I've recently installed fedora on my laptop, which has a SiS 630 graphics card, and have noticed that some of the 3D stuff is a bit corrupted, for example when running glxgears you can see some gears through others, and when using tuxracer the penguin appears to be lots of floating triangles making the shape of a penguin, but kinda see-through in parts... I've updated my driver as indicated on http://www.winischhofer.net/linuxsisvga.shtml, but it doesn't seem to make much difference... has anyone else had any similar problems, or know how to fix it?
I had RH8 before this and 3D wasn't fast, but it looked coherent at least!
