Window doesn’t redraw correctly sometimes when using compiz, but if I switch to another window then switch back, it redraws, this problem occurs with any type of windows, it’s annoying. I am using compiz 0.8.2 on my DELL 1420, with a Nvidia 8400M GS video card and Nvidia driver of version 180.44. Once upon a time, I can run compiz on this computer without any problem, but that’s really a very long time ago, with a very old nvidia driver and very old compiz fusion.
