There is a known bug with the 9625 and the new 9626 beta drivers 
pertaining to the implementation of the TFP (texture from pixmap) 
functionality. This appears to result in various issues with compositing 
managers, whether it be compiz, compiz-quinn or beryl.

nVidia is aware of this and is hopefully moving forward with a fix.  It 
appears to be related to the amount of video ram available. So it will 
show up at varying times depending upon how much video ram is being used 
as a consequence of how many apps/windows are open, how many displays 
are being run (ie. single display versus TwinView), and so forth.

I posted a "me too" bug report on this yesterday here (#13):

and take note of post #4 by jamesjones.

Many of the reports that I have seen in various forums regarding the 
presence or lack of window decorations, white/black/blank windows/cubes, 
etc. may be an outcome of this underlying issue.  The white window/cube 
issue seems to be more prevalent with XGL installations as opposed to 
AIGLX systems.

Note that previously, I had used XGL on my FC5 system with the current 
stable nVidia driver (8774) and had compiz-quinn running without 
problems. So we seem to be in a bit of transition with nVidia's current 
beta drivers supporting TFP and the use of AIGLX.

HTH,
