I'm going from poor to unusable performance in chrome and now you've mentioned paint event I'm thinking maybe I added something like this recently. If I tap and drag to move a view down but it changes thebackground of one of my list items then it jerks and lags as though it's the event that killed it. Will take a deeper look tomorrow into what's being fired. What sort of stuff did you uncover yourself?
mmm I don't have any painted events for any of the components on my homepage. Removed shadows in 2.1b3 and it sped things up quite considerably.
I just changed 2.1b3 to 188.8.131.52 again and it's absolutely lightning fast in comparison.
What happened in 2.1b3 that made it run like crap on both iOS and Android/Android Chrome? Looking at the list of things it talks about improving performance for odd events but other bits have killed my app making it unusable.
