What about Option "XaaNoPixmapCache" and/or Option
"XaaNoOffscreenPixmaps"?

One possible cause for such corruption is forcing the wrong amount of
video RAM in the device section. If that's not it, it's probably a
radeon driver 2D acceleration bug which should be fixed in current DRI
and XFree86 CVS. You could try my DRI CVS snapshot packages at
deb http://penguinppc.org/~daenzer/debian/dri-trunk/ ./
but then you'd have to figure out how to integrate the nvidia driver
with those.
