When using a simple Map() on the MainPage of an Application, if one pushes a Page with another Map ontop of it, it will crop an image of the previous Map() that then sits ontop of the new Map() which renders the page quite difficult from a usability standpoint.
Looking through the View Hierarchy, there does not seem to be an additional view that contains the previous Map view. I've gone ahead and attached this as well within the sample project.
Attached with the reproduction is a Debug.keystore that already has been signed to the api key in the sample
PLEASE NOTE: THIS SEEMS TO BE ONLY ON PHYSICAL DEVICES
1) Download the sample
2) Run the project
3) Click "Map"
4) Notice the maps are at first synchronized, but then once you move the map you can see the overlapping effect.

Sample uses 220.127.116.11-alpha1, but can confirm it does the same behavior on previous stable versions

Information about my package
Runnging the repro I get an exception: "Event registration is overwriting existing delegate. Either just use events or your own delegate: Xamarin.Forms.Maps.iOS.MapDelegateMapKing.MKMapView+_MKMapViewDelegate." Code looks reasonable. I wouldn't expect this exception.
Jon can you send me a screencast or screenshots so i can make sure i m seeing the same as you?
Cannot replicate on Nexus 5 using latest 188.8.131.5276 stable thus marking Invalid.
