Swift 5, Xcode 12.5 CA Layer messages while playing video

Hi guys, hope all is well. I’m making some changes to my launched app, redesigning Home Screen and adding a How To video. I have a collection of buttons in stack view (which is set to clear). When I click the button to play the video I get these messages in debug panel:
**changing property masksToBounds in transform-only layer, will have no effect** **changing property allowsGroupBlending in transform-only layer, will have no effect**
Don’t know what to make of it. I’m playing video with this:

let player = AVPlayer(url: URL(fileURLWithPath: url))
        let vc = AVPlayerViewController()
        vc.player = player
        present(vc, animated: true, completion: nil)

Any idea why this is happening? Can I safely ignore it? It is not an error message.
Thanks a lot!
