Using stock Intrepid 8.10 Intel driver on a Lenovo X301 (Intel GMA
X4500MHD) I can use the Displayport (with both mirrored and virtual
monitor) however with the intel X drivers and compiz I get all sorts of
missed re-draw events when windows launch. When windows launch they will
be partially drawn. 'Wiping' another window over the area fixes the
damage.
This redrawing problem disappears if I switch back to the RGB cable
(same BENQ 20" monitor) with compiz, or if I use the Displaylink cable
with metacity. How can I tell if this is an intel driver bug or a compiz
bug?
Nothing in the Xlog.0.log, acts like no errors occurred (version number
and hardware snipets below).
