Thanks for the clarification. So whatever action that you perform in the callback (Thread.sleep, big computation, etc.), should be run on the event-dispatching thread. This should freeze the GUI of your application, but definitely not Xorg as a whole. I'm going to mark this as a Xorg bug for now, but it may turn out this is a bug in Java, or maybe even in multiple graphics driver.
