Comment 13 for bug 328484

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).

Aaron.
