Seeing this in my game made with Unity 2017.2.0f3 and an iPhone X running iOS 11.1. The top and bottom ~1 cm of the "world" background, of the camera texture, are messed up. The top is showing a portion from the bottom of the screen, as you can see here with the countertop and sink up there. And it looks like the bottom is showing a portion from the top of the camera image. It's a little difficult to tell here with the virtual arrow in the way and the ceiling being a plain color, but I observed it on another friend's device that showed it more clearly. Anyone else experiencing this? I can't tell if that's what this PR on the plugin source repo is about. I'm not familiar with the AR camera rendering details to know what's likely causing this.
