Description of problem:

While using compiz/nvidia windows decorations disappear after minutes or hours -
sometimes it's just a few minutes, sometimes they disappear after a few hours -
I don't know what's related to it.

Version-Release number of selected component (if applicable):

metacity: 2.18.5-1.fc7@i386

How reproducible:
hard to reproduce, but after minutes / hours it happens, usually it happens 2-3
times per day, but today it happened 5 times within 2 hours.

Additional info:

I use latest nvidia drivers from freshrpms.net (don't bite, I just want to have
eye candy desktop ;-)) with fedora/updated packages, windows decoration is
Clearlooks - default one. My everyday work includes browser (Firefox 2.0.0.4
from ftp.mozilla.org as that one shipped with Fedora renders fonts incorrectly),
Zend Studio 5.5.0, Evolution, OpenOffice. Sometimes I use virtual machine
through vmware.

Hardware: Dell Latitude D620 with T7200 Core 2 Duo 2GHz, 2GB RAM, nvidia on
board, display resolution is 1440x900.

What I have noticed - usually windows decorations disappear when I am trying to
close an application (ie. vmware, open office, or even nautilus windows) - but
it happens randomly - sometimes I can work for 5 hours and everything is all
right, sometimes it happens every 5-10 minutes. Looks like there is no rule -
just happens :)

if you need any more information - you're more then welcome.
