Bug Description
From time to time a single white pixel shows up in the top-left corner. The pixel stays above fullscreen windows, and xwininfo reports whatever is under the pixel (Unity panel, VLC player). Restarting Compiz gets rid of the pixel.
I tried hard, but unfortunately I haven't found a way to reproduce it.

I experience this problem on Oneiric as well, both with fglrx and with Intel drivers.
The white pixel disappears if I activate the workspace switcher (Super+S) but comes back as soon as I exit it (Super+S again). The white pixel disappears for a short moment if I navigate to a different workspace with Ctrl+Alt+Arrow.
