Display bug with WebKit / HTML object video and Qt::WA_TranslucentBackground
-
Dear All,
I search a solution to solve my problem of video / webkit and transparent window.
I display a video in the WebView which is include into a MainWindow.
All is ok except if i put the window background transparent... Here, the video do not display but i could click on and listen the audio.
Did someone has already encountered this problem and found any solution?
Thanks.
