[Bug 779123] [NEW] Compiz ram usage increases over time


Public bug reported:

Binary package hint: compiz

When compiz starts, it uses about 50mb of ram, but that amount increases over time. I left it running for 8 hours, and the memory usage was 1,6 gigabytes.
How to reproduce:
1. Start compiz
2. leave it running for a longer period of time
It will use about 50mb of memory at start, the usage will grow over time. After 15 minutes it will use 100mb.
