Summary:
Launching app from SpringBoard has noticeable delay.

After tapping of an app icon is done, app-launching animation should immediately start. Instead, the device waits for the icon to be overlaid with grey rounded-rectangle first, then the grey transparent overlay fades out and app launches.

As a result, the app launching experience feels far less responsive.

This lag seem very likely to be introduced alongside with a workaround of detecting short tap, press or long-press in Force Touch API.

Steps to Reproduce:
1. Tap any icon on home screen

Expected Results:
After finger is lifted, app immediately starts launching.

Actual Results:
After finger is lifted, the device waits for the icon to be overlaid with grey rounded-rectangle first, then the grey transparent overlay fades out and app launches.

The app launching experience feels far less responsive.

Version:
iOS 9 Beta 3 (13A4293f)

Notes:


Configuration:
Any iOS device running iOS 9 beta 3 (13A4293f)
