[compiz] minimize plugin artifacts

[Element]

Hello fellow compiz users/developers,

Since the beta nvidia drivers have been made available, I have attempted 
to get compiz working properly on my system. However, I have been unable 
to resolve one issue with regards to the minimize plugin.

Minimizing a window on my system produces artifacts of window 
decorations as illustrated in the following image:

I had posted a bug to the fd.o bugzilla some days ago but while waiting 
I thought maybe others on the list may have had this issue and already 
found a solution.

I am using the .2 version of compiz on gentoo xorg 7.1. I have already 
attempted rebuilding glproto/mesa/xorg among some other things as well 
as re-installing the gconf schema to no avail.


Thanks in advance
