Yes, this explicitly causes the same NULL proxy problem. I really don't see how a leave event is appropriate here. That would kind of change what a leave event means because the pointer may not have left anything. Since we don't want to send to all the other resources associated to that pointer, this leave event would also be resource-specific and not pointer-specific. Also, I would expect clients to call wl_proxy_destroy immediately after calling wl_pointer_release anyway and in this case they simply won't get anymore events. --Jason Ekstrand
