Has anybody solved the problem in ST 2.1 on iOS (or even on Android) pointed in subj? After upgrading to version 2.1 I noticed that on iOS list twitches/flickers during the scrolling. Even on small data. It's really noticeable and annoying. For instance, check out Kitchen Sink for 2.0.1 and 2.1:

The twitches are so noticeable it feels like a major performance degrade. I think this happened after their re-implementation for the list in order to handle large lists by recycling the dom elements. The little twitch happens exactly when a dom element leaves the screen. Hopefully this can be taken seriously as prioritized issue!
