      Description

      QWaylandShell surface is empty when the gst-launch streams video to it on the Elina Linux. All works OK with Weston.

      Reproducing steps:

      1. Compile the minimal-qml compositor, copy to the target and launch it by run-compositor.sh script
      2. Copy a test video (1920x1080 h264) and the run-client-test.sh script to the same directory in the target
      3. Start gst-launch streaming by the run-client-test.sh
      4. Add in the minimal-qml GUI a new Wayland surface

      Expected results: A surface is created and the video is displayed on the surface

      Actual result: An empty surface is created

      NOTE: If the Weston used as a compositor instead of the minimal-qml, the video is displayed successfully on the surface. The GStreamer version is 1.8.3.
