I have a Rage 128 video card and, despite my efforts, it experiences graphical glitches and outright hangs when doing any OpenGL video.
I tried fiddling with the PLL timings and putting it into AGP 1x mode, to no avail (but considerable performance loss... my tweaking got glxgears as high as 550fps but now, when it runs for five seconds without hanging, it only gets 300).
Ideas?

x11-base/xorg-server-1.2.0-r2 (compiled WITHOUT the r128 VIDEO_CARDS flag set, fixing that now though I doubt it's the problem)

I'm not sure I can really help here, but older versions of X (up to 7.0) worked well on my R128 equipped PB G4 500. Can I see your X config?

GLXGears really isn't that useful as a performance indicator, I would try to play games (like tomatoes or crack-attack) and see how that runs instead.

The games that don't hang or crash immediately hang within a few seconds of starting. glxgears and glmatrix are the only remotely stable OpenGL apps...
