Public bug reported: I didn't have this problem in 12.04. The system boots fine but after some time of opening and closing windows, the system becomes painfully slow. The animation to close a window takes around 3 seconds, it starts when you click the close button, but then the animation plays in like 2 fps. and skipping frames (it happens too when you restore, minimize, etc). The notification popups become very very slow too. It is almost impossible to alt+tab also. In every move, compiz takes the whole core. Idle around 30%. But it doesn't start like this.
