      Description

      Hello,

      I'm experiencing what appears to be a bug in QVideoWidget. When I resize the window containing the video the image becomes stretched. During the resize, while the mouse is pressed, the video frame flickers between the stretched state and a state where its aspect ratio is maintained, and stays stretched when I release the mouse (see attached image).

       

      A basic version of the widget I'm using to replicate the issue is shown below (using PySide2):

      class Editor(QWidget):
      
          def __init__(self, video_filename, parent=None):
              super().__init__(parent)
              main_layout = QVBoxLayout()
      
              video = QVideoWidget()
              video.setAspectRatioMode(Qt.KeepAspectRatio)
              main_layout.addWidget(video)
      
              self.player = QMediaPlayer()
              self.player.setMedia(QUrl.fromLocalFile(video_filename))
              self.player.setVideoOutput(video)
      
              self.setLayout(main_layout)
              self.player.play()
      

       

      The system I'm running this on is Ubuntu18.04 with the X11 window system and GStreamer1.15.5
