      Description

      When resizing QML application, the contents flickers and the window can be blank sometimes. It also happens that the window is blank when started.
      (See qtbug96405.zip-video.mov)

      Adding this to main.cpp

      setGraphicsApi(QSGRendererInterface::OpenGLRhi);
      

      and QML application is as simple as

      ApplicationWindow {
          width: 360
          height: 240
          visible: true
          Button
          {
              anchors.centerIn: parent
              text: "Hello my world"
          }
      }
      

      How to reproduce
      Use qtbug96405.zip and try to resize.
