      Description:
      The VideoGraphicsItem app, which is expected to render and play a video, does not display the video correctly on Android devices. Instead of rendering video frames, the screen remains static.

      When the user rotates using the scroll pane at the bottom, a flickering black screen appears momentarily during the rotation. As soon as the user stops rotating, the flickering disappears, and the screen remains static again.

      Steps to Reproduce:

      1. Build and deploy the Video Graphics Item Example on an Android device.
      2. Play the sample video included in the example.
      3. Observe that the video is not rendered.
      4. Rotate the video using the scroll bar at the bottom.
      5. Notice the black flickering screen during rotation.
      6. Stop rotation → flickering vanishes and video remains invisible.

      Expected Result:

      • The video should be rendered and played smoothly inside the VideoGraphicsItem.
      • Rotation should not cause black flickering.

      Actual Result:

      • No video is displayed.
      • Flickering black screen is visible only during rotation gestures.
