I am attempting to make a macOS app to show a large popup with no titlebar and a transparent background that spans the entire active display. Currently, I am attempting the last part, with the sizing. I used an example on the relevant developer documentation page. This is the code I am using in my App struct: @main struct MakeGoodChoicesApp: App { ... var body: some Scene { ... Window("Make Good Choices", id:"popup") { PopupWindowContentView() .ignoresSafeArea(.all) } .windowIdealPlacement {_, context in return WindowPlacement( x: context.defaultDisplay.bounds.minX, y: context.defaultDisplay.bounds.minY, width: context.defaultDisplay.bounds.width, height: context.defaultDisplay.bounds.height ) } } } When running my application and using some code to open the popup window, I get the following result: I would expect the window to expand past the safe area, but it seems as if macOS clamped the window's size down to inside the safe areas. I would appreciate any help, many thanks!
