      primary UHD-screen scaled to 200%, secondary FullHD-screen scaled to 100% (same issue on both screens)

    Description

      1. Build and run the WebEngine Quick Nano Browser example.
      2. See the scrollbar on the right and bottom of the window.
        It's much too big:

      The scrollbars should have the same size as in a native application. With Qt 5.8, this worked correctly.
