Comment 97 for bug 720446

The bad thing about this isn't necessarily that compiz leaks memory, but you can basically watch your desktop getting slower and slower. If I reboot Ubuntu/Unity after a week, this feels like a new machine for me.

The next day compiz seems to iterate over more objects than it needs to already. This gets worse every day. First I thought the "lagginess" is due to swapping activity, but it isn't. This is pure userspace CPU load by compiz, slowing down all activities regarding the desktop and its windowing.

If you keep your actions within a window, everything is fine.

I guess we should create a new bug regarding this, .. it doesn't look like this is being reopened.
