XEventsQueued(disp, QueuedAlready) only returns the number of events currently in the queue and does not flush new events. So this must happen elsewhere and if it does not we will never see any events. i noticed this bug when removing the call to glXSwapBuffers(). Fix this by using XPending() instead as this flushes new events if the queue is empty before returning the length. see https://tronche.com/gui/x/xlib/event-handling/XEventsQueued.html and https://tronche.com/gui/x/xlib/event-handling/XPending.html
