Black borders in ARCamera view

March 2, 2018 - 2:42am #1

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

You should link a photo of your problem, I don’t understand the problem you say, and I don’t think is related to the black border bug

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.
