Bug Description
Binary package hint: compiz
I have a fresh, up-to-date i686 gutsy install and an NVIDIA GeForce Go 7900 GS on a Dell XPS M1710 laptop. With compiz enabled, I occasionally see an artifact where the entire screen "blinks" to black. Some days it happens not at all; other days it may happen several times, even in the span of a few minutes. Sometimes the blink seems to start from the bottom of the screen and then go up, as if the video card renders the bottom first or something. Other times it seems as if it is only the bottom half that blinks, but that could just be my eyes failing to pick up the entire event. Unfortunately I haven't noticed the event being correlated with anything else.
I am going to try to capture the event with a desktop session recorder, but I'd be surprised if that works. If not, I might try to record it with a real camera.

I have a similar issue with my laptop Asus F3JM (15.4" WXGA, GeForce Go 7600, Compiz Extra enabled). It happens sometimes without warning. Maybe I've used the notebook for more than an hour and nothing has append and suddenly the monitor starts blinking. I noticed that it happens especially after I have launched OpenOffice.
