It sound strange, isn't the "_deliverMoveResizeEvent" should be called on the resize only, why it affect the mouse move events which posted later? the new flag NSWindowStyleMaskFullScreen will work when the window was moved to the full screen, what about the case when the window will moved from the full screen -> the mouse will appier outside of the window?

BTW we also have a call to synthesizeMouseEnteredExitedEventsForAllWindows in the windowDidEnterFullScreen which should do what you tried to achieve in the latest patch, why it does not work?
