Turning off animation conserves large amounts of memory, but after
opening about 50 (can't remember the exact figure) windows on a
3200x1200 dual head machine (which is not uncommon for me given my work
pattern) on a 320MB video card the problem still comes back for me. As
far as my extensive tests concluded,  there is nothing you can turn off
in compiz that fixes the problem. A particular choice of settings may
reduce the memory loading and so push the problem beyonda persons
practical use limit so they don't bump into the problem in normal
circumstances, but the problem is still there at the same memory
threshold.

The following test shows it to be a memory issue: Open windows until the
problem appears. Now close windows until the problem goes away. Open one
more window. As you vary the size of that window you will find a window
size that is at the threshold of the problem. Make the window bigger and
black windowing occurs. Reduce the window size, the problem disappears.

This, or related problems has been a known issue for many many years.
Back in 2006-7, this or similar bug existed, known as the  NVIDIA Black
Window Bug, though whether the bug was actually a NVidia one or a compiz
one was in question.  The workaround was to change the direct rendering
options that existed in compiz at the time. It was suggested that the
NVIDIA Driver 100.14.19 fixed it. Maybe it did. If it did the bug, or a
similar one was reintroduced at some stage, or something was never
properly fixed. I don't know. But it is clear that this bug, at least as
I am experiencing it, is memory related.

Bug description:
  Ubuntu 12.10 64bit (updated from 12.04) / NVIDIA GeForce 8 proprietary
  driver.

  This bug happens to me from 12.04 from some update I think.
  It appears mostly when I open a new application and only ocassionally.
  As temporary "solution" creating some other event like opening Unity dash or opening some next window, etc. fix it. Then window content is refreshed and I can see all correctly.
  Same with stable and experimental nvidia drivers.

  Screenshot of this bug is attached.
