FPS hit when adding UIView containing buttons to Metal app on AppleTV

The FPS drops by 4 on AppleTV 4K (8 on HD) when I enable a UIView that contains 6 UIButtons (Type=System), each with a SF Symbol as the background image and no label.

Is this expected?

Are there any suggestions for the most performant way to mix UIKit controls with Metal?
