#0 0x0000003dc304244d in clutter_actor_contains (self=0x75309f0 [StButton], descendant=0xdecafbad) at ./clutter-actor.c:7877 #1 0x00007f9db240faf8 in st_widget_leave (actor=0x75309f0 [StButton], event=0x383e5e0) at st/st-widget.c:647 That would appear to indicate that the pointer moved out of button, and moved into a bug in clutter or your video drivers.
