Repro for issue

When running iPhone apps on an iPad it's possible to get a "ghost" status bar covering the screen when rotating in a specific order.

ensure the app is running at 2x
Rotate the app to the left
Click the 1X button 
Rotate the app to the right
You will see a black bar near the top of the screen that doesn't go away even when navigating

I've included a sample but it's really just file -> new project.

That does not sound like something that would be specific to Xamarin.iOS (i.e. an iOS bug).

@Paola, can you check if the same happens in Xcode using a similar test case in ObjC ?
Comment 3 Paola Villarreal 2014-10-27 15:46:07 UTC
This also happens on an xcode project. 

To reproduce: 

1. Create a new single view (iPhone) project
2. Run it
3. Make sure the app is running at 2x
4.Click the 1x control 
5. Rotate right.

Closing this bug.
