Bug 45721

Compiz begins to increase memory usage from 105.6 MB at Boot to 250MB+ after an hour of use, eventually Compiz crashes and logging out and fixes the issue.

From boot Compiz memory usage Sky rockets and goes up until the proccess crashes; this can happen randomly. Chrome becomes to be sluggish and there's considerable latency between input and final result of those actions; simple usages such as typing can have a 1-5 second delay depending on system boot time.

After a un determined amount of time the process (Compiz) crashes and typing 

compiz --replace & does not effect the memory usage and sluggishness. I believe Compiz is an OpenGL wrapper for Unity and is bundled with NVIDIA drivers. In addition the recent NVIDIA 302.17 drivers seem to have caused the issue.

CPU, Module and RAM info attached.

The only work around is a hard reboot or log in/log off.
