When creating a UIImage from a SwiftUI View, using a UIHostingController and a UIGraphicsImageRenderer, the resulting image is offset/clipped.
The issue started appearing when building with Xcode 13.0 (13A233) after having worked previously when using Xcode 12.5.1.
See the attached SnapshotBug.swift consistently showing the problem.
The offset/clipping also seems to be device orientation dependent...

Reproducible in Xcode 13.0 (13A233), iOS App, iPhone 13 Pro iOS 15.0 Simulator.

SnapshotBug.swift
```swift
import SwiftUI
import UIKit

struct SnapshotBug: View {

    @State var renderedImage: UIImage?

    var icon: some View {
        Image(systemName: "gear")
            .resizable()
            .scaledToFit()
            .frame(width: 40, height: 40)
    }

    var body: some View {
        VStack(spacing: 20) {
            icon
                .border(.red)
            if let renderedImage = renderedImage {
                Image(uiImage: renderedImage)
                    .border(.red)
            } else {
                Text("An identical image should appear here")
            }
            Button("Render image") {
                renderedImage = icon.toUIImage()
            }
        }
    }

}

extension View {
    func toUIImage() -> UIImage {
        let controller = UIHostingController(rootView: self)
        let view = controller.view!
        view.bounds = CGRect(origin: .zero, size: view.intrinsicContentSize)
        view.backgroundColor = .clear

        let renderer = UIGraphicsImageRenderer(size: view.bounds.size)
        let image = renderer.image { _ in
            view.drawHierarchy(in: view.bounds, afterScreenUpdates: true)
        }
        return image
    }
}
