Weird, these symptoms sound exactly like what would be expected with a
compositing manager... I suppose you're sure there isn't something like
even just xcompmgr -a in your X session startup scripts? :}

I notice Option "GARTSize" "128" in your X configuration - does the
problem persist without that?

If this doesn't help, please also provide the full output of glxinfo
when the problem occurs.
