As, still, no one seems to be doing anything about this (including me - it is beyond my expertise), is there anyone who can reliably find a way to bypass it. This sort of problem has been a regular show with Compiz+Nvidia, and seems to rear its head in a number of guises. There was a very similar old bug about 5 years ago, the Nvidia Compiz “Black Window Bug” which was fixed back in Feisty using an indirect rendering, but that slowed things down. Maybe the old problem is back? I don't know. But it is painful and it is a serious problem. And it is a Compiz problem, not really an nvidia one.

Nvidia graphics card with proprietary driver. Not all the time, but maximizing windows sometimes results in a white window. Sometimes switching between windows (not necessarily maximised) does the same. The window borders are there but the body of the window is white. Resizing the window smaller sometimes makes it redraw. Minimizing other applications sometimes makes it redraw. The white window is most often the focussed window, but sometimes windows behind the focussed window go white too. Once an application has gone white, this seems to encourage other windows to do the same. Minimizing all windows, reactivating the required window and perhaps resizing will bring the window contents back. I don't think this is restricted to specific applications. I've been able to duplicate the problem with Firefox, Thunderbird, Nautilus, Synaptic, Terminal, Geany, Nvidia Settings and others. It's not Unity. If I switch to Classic I get the same problem, although perhaps with slightly less frequency. Switch to Classic with no effects and the problem goes away. So I suspect a combination of Compiz and the Nvidia driver that comes with Natty.
