    Description

      When a menubar spans across displays using different DPIs then opening menus on either display can show the menu in the wrong place. With the example attached, move the window so it cuts across different displays then open a menu on the one side and then one on the other side and observe that one of them is placed incorrectly.

      This is only happening when HighDpi is enabled as it is not a problem without it.
