Same problem, when I switch effects on (normal or extra) maximising, unminimising, tab switchin became very slow = have to wait 1-2 sec before something happends. For those 1-2 sec computer basically freezes. I have Dell Studio 15 with ATI mobility radeon HD 3450. Open source ati drivers do not solve anything because 3d support for my card is not included. I think this bug really decreases the desktop experience. Otherwise ubuntu 9.04 is simply great!
