Bug description: Over time (usually with uptime of 5-6h) compiz occupies a large ammount of virtual memory size and when it reaches around 1.5GB it starts filling up swap partition thus reduces overall system performance. Funny thing is that resident memory it uses is around 50MB and doesn't get larger, at all times I have at least 1GB of free RAM memory available (on 2GB total).

System enviroment:

chipset: GM965
system architecture: 64bit
xf86-video-intel: 2.7.99.902 (Jul 13th)
xserver: 1.6.1.901
mesa: 7.4.4
libdrm: 2.4.11
kernel: 2.6.31-rc3
linux distribution: Arch linux
machine: Dell Vostro 1310
display connector: LVDS

Steps to reproduce:

Open a window in nautilus and start resizing it continuosly, if you trace the amount of virtual memory that compiz occupies with "top" you will see that it is rappidly increasing. It will fill up swap partition very quickly (measured in seconds, a minut max) and it will degrade performance or lock up the entire system.

Additional info:
i915 and intel-agp are build directly into kernel and not as modules, KMS is enabled. This bug affects 2.6.30.1 kernel also and previous xf86-video-intel drivers. There are no dmesg warnings or related messages...
