I found myself thinking the same. It must have something to do with this changelog item
- Performance has been improved (as well as tearing and out-of-order rendering have been fixed)
I think we render more frames now, but it’s definitely slowing things down - in a 24fps vs 60fps sort of way.
If you contrast this on X10II to native Android, even on a much older device like Xperia X - X is super snappy and smooth in scrolling. I wonder if it’s even possible to reach this rendering speed in AppSupport container, maybe @jovirkku knows?
