The transition animations while flipping through widgets got really jerky after the latest firmware update. Everything works well if I only have Garmin's own widgets installed but if I install even one third party widget, transition animations to it and from it disappear totally. Also, if I have a third party widget before heart rate widget in widget loop, heart rate widget doesn't plot anything in the diagram. Third party watch faces make the watch feel jerky, too.
Overall, the latest update made the watch feel less responsive and smooth than before.
