It is possible that the MFC screen needs to be told to repaint. If so, try sending a WM_PAINT message to the screen by using CWnd::Invalidate(); PhilT -Original Message- From: osg-users [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of padd...@gmx.net Sent: 31 January 2015 10:55 To: OpenSceneGraph Users Subject: Re: [osg-users] 答复: Blank screen Hi Clement, about your second screen: if you create your OpenGL context on the external screen - have you checked if this screen also has hardware acceleration?

Hi Philippe, Could you try removing the #define GL_ARB_vertex_buffer_object line from the include/osg/BufferObject header to see if that allows the Qt header to compile fine. Robert.
