Please describe the problem:
Xorg server 1.5.3 eats all cpu (on one core) when running gnome desktop.

as per https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/319813
it looks like its a Xorg-server bug, but it is only fixed in development release of Xorg
and it appreas to happen only when running gnome 2.25.x-2.26.x (fxce and fluxbox and gnome 2.24.x are fine)

personally, I dont know what causes this to happen

First of all, i am not even sure its gnome-session's bug, so forgive me for my uneducated guess.
second, i know its xorg bug, but since it happens only in gnome, and gnome 2.26 is stable, it would be great if gnome could fix it before xorg-server 1.6.0 comes out.,

Also, I build gnome from scratch, so perhaps its my failt that it behaves this way, maybe I am missing something ?



Steps to reproduce:
1. start gnome-session
2. check CPU usage
3. 


Actual results:
CPU usage does to 100%

Expected results:
CPU usage be NOT 100%

Does this happen every time?
everytime
