in iOS 12, I can set up an ARSCNView as a subview of my main view with the following: lazy var sceneView: ARSCNView = { let sceneView = ARSCNView(frame: .zero) sceneView.delegate = self sceneView.backgroundColor = .clear sceneView.scene.background.contents = UIColor.clear return sceneView }()- the result is that sceneView is fully transparent: that is, the contents of the view show through it.In iOS 13, if I set s sceneView.scene.background.contents = UIColor.red or any other colour, the sceneView show that solid colour, but if I set it to .clear I get a black background. It seems not to be respecting alpha.Is this a bug, or am I missing something?thankswil
