This does indeed sound like a separate bug, most likely in the radeon
driver's EXA Render acceleration code. As the XAA issue is already
covered in other Debian bugs, let's focus on this one here. Could you
please report this upstream at http://bugs.freedesktop.org as well,
including all this information and possibly attaching screenshots of the
corruption?

Take your time.

FWIW, the hardware issue is probably yet another separate bug, I assume
it can be worked around with Option "SWcursor".
