    We had 3 widgets: A, B and C. A is the main window and parent to B and C, B is the container widget for a real time rendering engine. Widget C contains all kinds of QT Quick items and it flows above Widget B.

    We want Widget C transparent to both A and B, and we know the conventional way to do it. But the conventional method fail to do the work if Widget B is the container of a render engine.

    Any suggestion to make the window opacity mechanism work in this situation?

      Hi,

      What version of Qt are you using ?
      On what operating system ?
      With what graphic stack ?
      What is that rendering engine ?

          Would it be possible for you to provide a minimal compilable example to reproduce the behaviour ?
