[Bug 752445] [NEW] Intermittent white window contents when maximizing/switching windows


Public bug reported:

Binary package hint: compiz

Fresh install of Natty Beta. Nvidia graphics card with proprietary

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

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.
