I'm developing a chat app using Ionic 1.3.1, the same code works perfectly on desktop browsers but has problems on real devices (android 6.0.1/ios 10.3.2), that's why I think this is a ui-scroll bug.

No matter which values I use for buffer-size and padding, when I reach the top element in the buffer (eg. index -40) it loads buffer_size elements and jumps to the new top element (e.g. index -60) then loads other buffer_size elements correctly.

Also, when I set the same height to every element, works fine on ios, but this is not a possible solution since every message may have different heights.

I don't have enough time to provide a repro, can you please give some tips on what I can look at to try to solve this?

PS: Thanks for developing this, switching from ng-repeat to ui-scroll has improved performance hugely!
