I tried to turn on composite manager on my XFCE desktop with EXA rendering on X11. It result to wrong rendering (or displaying) background images on some pages with complicated backgrounds and css.

My OS is Archlinux, all packages up-to-dated.
Here is my hw report, if is it useful for you:

Note: if i switched xorg to use XAA renderind, composite is fine. This is only happens if i using EXA rendering methode.

Reproducible: Sometimes

Steps to Reproduce:
1. setup xorg.conf to use EXA rendering
2. turn on XFWM compositor
3. run firefox and go to some page, ie archlinux.org and scroll down and up
Actual Results:  
the menu bar will be crashed, moved down or so..

Expected Results:  
background should be right so as have to be
