An update: I reverted to the default settings in Compiz (by going preferences -> reset to default in ccsm). The only changes I made after this were:
1. Have 16 virtual desktops in a 4x4 tile
2. Assign shortcuts for switching between desktops
3. Disable window decorations for maximized windows (use the appmenu instead)
4. Change the keyboard shortcut for toggle window maximization state.
I still see this leak. Again, I'd really like to see this bug resolved and would be happy to do anything to help fix it.
