@The Fiddler: The bhavior you mentioned doesn't have to do with the screen border issue. It is also triggered with a maximized window under a top panel when you move the pointer right on the line between the top panel and the window title. So this seems to be another bug (mayb of compiz' gtk-window-decorator?) unrelated to this one. (As it is there in the default configuration, it might actually apply as a papercut.)
