Comment 6 for bug 376092

When I run compiz, the cached memory grows continuously until the system becomes unusable. I suspect this to be a memory leak.
I've found that this is related to UXA, KMS used or not, and happens with all the driver versions I have tested:
-- The official Jaunty 2.6.1
-- The 2.7.0 from ubuntu-x-swat (launchpad)
-- The 2.7.99 from xorg-edgers (launchpad)

OpenGL version string: 1.4 Mesa 7.5-rc1 (happens with default Jaunty too)
X.Org X Server 1.6.0

This doesn't happen when using EXA or without compiz.

To reproduce:
Do some window open/close/resize/…
I use this bash line:
while true; do firefox & sleep 3; pkill firefox; done
You could see the cached memory grow quickly and about one minute after I'm out of memory (on 1GB).

The attachments and details of how I investigated are on the original bug report given as URL:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/376092

Summary:
This is neither related to architecture (both i386, amd64) nor (actual) kernel version (Jaunty official / 2.6.30-rc).

The external monitor doesn't play any role here.

It seems that the leak go with the resolution, bigger screen, quicker run out.

I hope to be complete…
