Bug Description:
---------------------
On gm45 with UXA enabled, there will be some problems when run arbnpot-mipmap. With the 'xcompmgr' off, the picture is out of the window.(As shown in the attachment)When drag the window away the picture still showing there, and if you drag the window back to the pic, that pic will be refreshed. If you change the window size, the pic will change correspondingly. 
With the 'xcompmgr' on, at first the picture is out of the window too. But if you move the window away there will be no pic outside the window. 

Reproduce steps:
----------------
1.enable UXA
2.xinit&
3. gnome-session&
4. mesa/progs/tests/arbnpot-mipmap
