    Description

      Starting an app with normal landscape mode shows the app correctly.
      However, when rotating the phone up-side-down, there's a black bar that hides a part of application.
      See screenshots as a reference.

      Normal

      Up-side-down (Black bar appears)

      The problem can be easily reproduced by using empty widget app and set 

      android:screenOrientation="userLandscape"

      in AndroidManifest.xml.
