I am running compiz 0.7.8 on foresight linux with an nVidia Corporation GeForce 8600M GT. When compiz is running screens are sometimes very slow to redraw. Clicking in the affected window seems to make it redraw right away. Same thing with resizing the window. This is not specific to any one app. It seems to affect Firefox, gnome-terminal, Thunderbird, etc.
