I have a brand new, 2012, 27" fully loaded iMac and after updating to 10.8.3 graphics are no longer smooth. When i switch spaces, the title bar (where the apple logo/file/etc is) goes blank and then resets to the new app that is in that window. Also, when pointing to the dock, which is on magnification mode, the dock animation stutters. This also happens when I start an app, the bouncing icon stutters! It is driving me crazy.
