Black borders in ARCamera view

Vuforia SDK Version: 7.0.47 - Description with steps to reproduce: I just updated my app from Vuforia 7.0.?? to 7.0.47, in Unity. The last version had no problems, but with the new update I encountered a problem only with iPhone 8 and iPhone X (I tested also iPhone6, iPhone SE, iPhone 5 and iPad 4 retina). I see a black border (with iPhone X on top and bottom, with iPhone 8 also on left and right) in the ARCamera view; Canvas images that are in the border instead are not covered by the black border. I tested the problem with a very basic app, and the results are in the screenshots I linked. The border also change in size when I put the app in background and reopen it. With the iPhone 8 sometimes disappear (for example now I cannot reproduce anymore the problem) Could you investigate? I use Unity 2017.3.1p2 Vuforia 7.0.47 OPEN GLES2, Portrait, IL2CPP, no strip engine code, "defer system gesture on edges" all enabled, hide home button on iPhone X enabled iPhone X IOS 11.2.5 iPhone 8 IOS - Development OS (Mac OS X, Windows, Linux): OSX - Mobile OS and Version: IOS 11.2.5 - Mobile Device Manufacturer and Model name: Apple iPhone X - Do the Vuforia Sample Applications show the same behavior?: Yes

I'd like to add that object placement on an image target is shifted with and without the black border.  When the black border is visible I believe the tracking is similar to Vuforia 6, without the black border (fresh app run, no backgrounding) the placement is wrong.
