hi, what i discovered in dealing with this issue is that you must call gdk_window_get_pointer() as the very last thing to do when processing the motion callback. calling it anywhere else in the callback code can cause backlogs exhibiting the behaviour you describe. from the manual: (http://www.gtk.org/api/2.6/gdk/gdk-Events.html#GdkEventMask) When using the GDK_POINTER_MOTION_HINT_MASK the server will only send a single GDK_MOTION_NOTIFY event (which is marked as a hint) until the application asks for more, by calling gdk_window_get_pointer(). can't see the demo code right now, so can't comment specifically on that, but i found that once i made the get_pointer() routine exist only once and as last in my motion callback, there were no delays whatsoever, it behaves as i want and expect. cheers, richard > When I compile and run the Scribble sample code, the motion_notify_event > responds slowly, which causes the drawing pen to "skip", even if I remove > the GDK_POINTER_MOTION_HINT_MASK.
