Comment 6 for bug 952887

This affects me.

Windows either become black or transparent. While "invisible", windows seem to work the same, and objects within it can be interacted with, just not seen. Acting with them does not affect symptoms.

* Ubuntu 12.10 (Quantal)
* nvidia-current 304.51
* xserver-xorg-core 1.13.0
* compiz 0.9.8.4
