current code

        #if !os(watchOS)
        if #available(tvOS 10.0, *) {
            let format = UIGraphicsImageRendererFormat()
            format.scale = scale
            let renderer = UIGraphicsImageRenderer(size: size, format: format)
            return renderer.image { context in
                color.setFill()
                context.fill(CGRect(origin: .zero, size: size))
            }
        }
        #endif

just render a color to image
it should add

context.cgContext.clip(to: rect, mask: mask)

before color.setFill()

and also, the result after using UIGraphicsImageRenderer is different from old version, the old version is fliped vertically
