I´m trying to develop a simple Augmented Reality experience overlaying an image over a tracked image. I'm using `ARImageTrackingConfiguration` and inside the `renderer` method I have the following: let referenceImage = imageAnchor.referenceImage; let image = UIImage(named: "art.scnassets/2.jpg") let planeNode = SCNNode(geometry: SCNPlane(width: referenceImage.physicalSize.width,height: referenceImage.physicalSize.height)) planeNode.geometry?.firstMaterial?.diffuse.contents = image planeNode.eulerAngles.x = -.pi / 2 // Add the plane visualization to the scene. node.addChildNode(planeNode);The tracking is performing well but the overlay image is suffering the flash effect you see on this [video][1]How could I avoid this effect?
