Public bug reported:

In Unity, (11.10, nVidia graphics card), when using multiple
applications simultaneously, for example: Chrome, LibreOffice Calc, and
Shutter, maximized windows often show nothing but blank white screen.

This doesn't happen on my set-up in Unity 2D or LXDE.  This also does
not happen in Unity on my ATI based laptop.

Firefox survives these issues only slightly better than Chrome, but does
generally survive longer into a routine session than Chrome, which will
go to complete white screen even when not maximized.

For most apps, working with them in any size but maximized, or
minimizing them and completely restoring them seems to help.

Also, I have another machine (a laptop) with an ATI video card and the
same exact actions in Unity, on 11.10, do NOT produce these same white
screen failures.

I apologize if package misreported, a bit of a newbie, but this is
clearly a problem specific to Unity (compiz?) on my nVidia based
machine, as same works perfectly on my ATI based machine.
