Steps to reproduce:

Based on high speed camera measurements (on a QRD 7x27 device), there seems to be a degradation in UX scroll performance of the Homescreen App.


Actual results:

Measurements on 1.2:
51 FPS 
Measurements on 1.1:
58 FPS

Per qualcomm's testing, the applist scroll FPS no longer has a v1.1 regression. Previous 1.1 FPS was 53 fps, current performance is 54 fps.

Can this be improved? Should we expect better performance from 1.2 (55 fps or higher)?
We're still working on performance, including scrolling, and we are aiming for 60 fps as the goal.  We just closed this bug because it was a 1.2 blocker.
