I found that setting the parentWindow property fixes the stutter I was experiencing. Specifically in my GameKit helper where I configure the game's root window I also set this property: func configure(with window: UIWindow?) { self.window = window if #available(iOS 14.0, *) { GKAccessPoint.shared.location = .bottomTrailing GKAccessPoint.shared.showHighlights = false GKAccessPoint.shared.parentWindow = window } }
