    Description

      The camera videoOutput preview just displays a white screen when compiled with the UWP 32bit VS2017 kit for Surface Book. It also shows below message:

      qt.winrtrunner.app: ASSERT failure in void __thiscall D3DVideoBlitter::blit(struct ID3D11Texture2D *): "The parameter is incorrect.", file qwinrtcameravideorenderercontrol.cpp

      Same app works fine when built using Windows 32bit VS2017 classic kit. It shows white screen only in UWP builds.
