I dont know how to report or diagnose, but i think it can be related to this bug: Every time my screen got blanked, almost all times i get garbage on screen. System works well, and even killing everything (Except X) and running unity --replace, i cant get my screen back. If i plug a external monitor to my notebook and reload / kill / unity and open metacity, screens back (Messed up), but i can work again. Ive a image of one of this crash (But the displayed image changes: A brightly white when wakeup from blanking and fades to this image after a time).
