    Description

      The default multimedia backend and graphics API for 6.5.0 is FFMPEG + D3D11. However, it causes crash, and the error message is:

      D3D11: Removing Device.
      failed to get textures for frame false
      Device loss detected in Present()
      Graphics device lost, cleaning up scenegraph and releasing RHI

      Running QML media player example can reproduce the issue. I have to either switch multimedia backend to 'windows', or change graphics API to 'OpenGL' or 'Vulkan' to make the example work. Also, macOS does not show the issue since its default graphics API is Metal.

      qputenv("QT_DISABLE_HW_TEXTURES_CONVERSION", "true"); does not help. Also, the QWidget based media player example does not crash, although 'Device loss detected in Present()' warning message keeps coming.

      The issue may be related to hardware, since some people say they cannot reproduce the issue I am facing. So here is my HW and OS specs:
