** Attachment added: "Unfocussed windows sometimes go white too ..."
   https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/752445/+attachment/1987678/+files/Screenshot-1.png

** Description changed:

  Binary package hint: compiz
  
  Fresh install of Natty Beta. Nvidia graphics card with proprietary
  driver.
  
- Not all the time, but maximizing windows 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 focus 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.
+ and the problem goes away. So I suspect a combination of Compiz and the
+ Nvidia driver that comes with Natty.

Title:
  Intermittent white window contents when maximizing/switching windows
