After a lot of digging around, I've been able to find the following solution/workaround: func scrollUp() { let app = XCUIApplication()     let relativeTouchPoint = app.coordinate(withNormalizedOffset: CGVector(dx: 0.5, dy: 1.0))     let relativeOffset = app.coordinate(withNormalizedOffset: CGVector(dx: 0, dy: -1))     relativeTouchPoint.press(forDuration: 0, thenDragTo: relativeOffset) }

After struggling with this issue for a day, I find the answer half an hour after posting. The solution is to replace the Form in SubForm with List, and it gives me exactly what I'm looking for.

I'm running into the same issue now. It was working great with .clipped().compositingGroup() previously. It's in a part of the app that I don't regularly use, so I didn't notice until today that this broke with iOS15.1. I'm also on Xcode 13.2.1, same broken behaviour in the simulator and on a real device.
