List twitches

[s.t.a.s]

REQUIRED INFORMATION


Ext version tested:

• Sencha Touch 2.1

Browser versions tested against:

• Chrome 23 (Windows)
• Mobile Safari (iOS 6)

Description:

• List in Sencha Touch 2.1 twitches during scrolling on both platforms, iOS and Android. But for iOS it's more important, 'cause it worked normally before (on ST 2.0.1).

Steps to reproduce the problem:

• Add a list with 50 list items and scroll it. Even easier, check out Kitchen Sink for 2.0.1 and 2.1:
  ST 2.1
  http://docs.sencha.com/touch/2-1/tou...html#demo/list
  
  ST 2.0.1
  http://docs.sencha.com/touch/2-0/tou...html#demo/list

The behaviour of scroll and list on iOS is different. On ST 2.0.1 it's noticeably smoother.

The result that was expected:

• List should be scrolled smoother, without twitches.

The result that occurs instead:

• List twitches during scrolling.

The list differs how it works between 2.0.x and 2.1.x, the code for 2.1.1 looks to be smoother than 2.1.0

Could you say when to wait this build?
