back from an app pressing the home button Launcher takes 3 seconds like being started for the first time.
Sometime when I press the home button after resuming the phone or editing from an application the Launcher seem freezer on my Frequently used app page loading the icons and the screen looks empty. After three seconds or so the empty feed appears and finally is filled with with my icons. Looks like app restared every time and reload configuration. In the same time frame you can notice the icon of the GPS capturing the position.
