Hey guys,
Sorry to disappoint but this is most probably not a bug.
Apple announced in WWDC they will be always presenting the top blue bar when an app is tracking your location in the background so you, as a user, would be able to have full understanding of which apps are using your location at a given time . . .
I hope Apple change this policy decision based upon feedback during the beta process.
It is definitely an ugly "solution".
There was nothing wrong with the previous triangle icon based system.

The related change of making all apps display the option of "while using the app" for location tracking is definitely a welcome and long overdue addition, however.
