Bug detailed description:
-----------------------------
It fails under gnome-session mode,and passes under X mode on Sugarbay with mesa 8.0 branch .

The result is unstable on Sugarbay with mesa master branch under gnome-session mode.I ran it 50 times. it failed 22 times, and passed 28 times. It passes under X mode.


Reproduce steps:
----------------------------
1.	Start  X
2.	Start  gnome-session
3.	Run:   ./arb_seamless_cubemap –auto

"under gnome session" actually means "under compositor" (gnome shell).
