We have no guarantees on the number of ::size-changed signals that we may receive, so the _sizeChangedWindow handler may run multiple times, which leads to multiple calls to meta_plugin_size_change_completed(). So double check the actor is not already being animated in the _sizeChangedWindow handler to avoid reentrancy. https://bugzilla.gnome.org/show_bug.cgi?id=777784
