[Blocking Requested - why for this release]:

Nominating this to block 2.0?. Its very likely that the end user will be opening multiple apps and then backing out to the home screen without force closing all the apps they have used. This will cause multiple apps to show blank pages when opening them, as well as DUT performace to slow down significantly.

Low user impact base on what we've tested and seen during triage.
Black screen shows for a split second upon app launch and soon recovers.

This is a blank screen bug and not a black screen bug. The blank screen always requires some kind of user input before it will go away.
