import SwiftUI

extension View {
    func standByMargins() -> some View {
        modifier(StandByMargins())
    }
}

private struct StandByMargins: ViewModifier {
    @Environment(\.widgetContentMargins) private var margins

    private var isInStandby: Bool {
        margins.leading > 0 && margins.leading < 5
    }

    func body(content: Content) -> some View {
        content.padding(isInStandby ? margins : EdgeInsets(top: 0, leading: 0, bottom: 0, trailing: 0))
    }
}

If you have full-bleed content in StandBy, it currently gets clipped. Applying the margins again seems to perfectly fit the content within the rounded rect. This modifier should only apply the margins in StandBy - every other location has margins that are zero (iPhone / iPad Lock Screen) or greater than 5 (e.g., rectangular on watchOS is 7 pts).

Example:

Without .standByMargins()	With .standByMargins()
