What steps will reproduce the problem?
(1) Enter tablet mode and open a few windows
(2) Tap on the circle button on the shelf to minimize all windows
(3) Tap on the overview button to open overview

What is the expected result?
After home launcher animation is over, all windows should slide into overview

What happens instead?
Home launcher animation and window slide in animation seem happen at the same time

Not sure if it also happens on M71.

Sammie, Weidong, could you take a look?
