I have the same problem on Natty. Consistently if I have more a couple of windows open at a time, one or more will turn white. Sometimes it's the active window, sometimes an inactive one.
My wireless card is: nVidia Corporation C67 [GeForce 7150M / nForce 630M] (rev a2)
I also had this problem on maverick when I upgraded to the nvidia driver from ubuntu-x-swat/x-updates. In maverick I was using the Ubuntu repo version of compiz.
