      The background of the splash screen is not transparent, although it is set to transparent in the respective QML file.

      Reproduce:
      Open "QtQuick Example - Window and Screen". Compile and run.

      Result: 
      Windows: The splash screen has a white background (see image below).
      Linux without Compositor: The splash screen has a black background. With a compositor it's transparent as it should be.
      MacOS (5.15 and 6.5): The splash screen has a white background.
      MacOS (5.12): As expected result (not affected).

      Expected result:
      The splash screen should not have a white background.
