    Hi I am trying to use the Media player example (http://doc.qt.io/qt-5/qtmultimediawidgets-player-example.html) to test out some functionality to add into my own program.

    However when I try to return to normal view after a video is full screen the feed goes black, the audio continues playing and I get the following error:
    void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x19ac3a0) ): Attempt to set a screen on a child window.

    Help about how to fix this would be greatly appreciated.

      Hi. Is that with Qt 5.5?
      I think its a bug. If you gooogle it seems KDE also suffer from it.
      Also its mentioned here

        Yeah it is Qt 5.5, on ubuntu 14.04.
        I saw one of the earlier bug reports that was closed (user submitted multiple bugs in one report), so I was hoping it was a something wrong on my end and that it had been fixed.
        Thanks you for pointing me to the current bug report though.
