Thanks. These messages are unusual and could result in things being left on screen:
clutter_timeline_set_auto_reverse: assertion 'CLUTTER_IS_TIMELINE (timeline)' failed clutter_timeline_set_repeat_count: assertion 'CLUTTER_IS_TIMELINE (timeline)' failed invalid (NULL) pointer instance But the only thing I can see in your screenshot that affects animation timings is the use of indicators.
