    Description

      This is an issue I have noticed on Qt 6.5.1 on MacOS and on Windows 11, however it is not present in Ubuntu 22.

      The code is as follows:

      Window

      {          id: root      width: 640      height: 480      visible: true      *color: Qt.transparent* }

      or

      Window

      {          id: root      width: 640      height: 480      visible: true      *color: "transparent"* }

       

      For Windows 11 and for MacOS the window is either white or black but never transparent whereas for Ubuntu 22 using color: "transparent" it does make the windows transparent this is an issue in Qt 6.5.1.
      When I try it with Qt 5.15.14 this color: "transparent" works for Windows 11, have not tried it for Ubuntu 22 and MacOS.

       

      Based on this I assume this is an issue with Qt 6.5.1.
