I believe it is caused by this: void makeTorus() { m_OSGWidget1->getManager()->setRoot(osg::makeTorus(t_ir, t_or, t_r, t_s)); m_OSGWidget1->getManager()->redraw(); m_OSGWidget1->repaint(); std::cout << "sharing 1: " << m_OSGWidget1->isSharing() << std::endl; } here you call the SSM redraw() function which will render the scene, but you call it from a function where you have no guarantee that any OpenGL context is active. Since the context is managed by Qt you can only issue OpenGL commands from those functions where Qt allows it - unless you have some means to make the right context active yourself, I don't know Qt's OpenGL support well enough to say if that is possible. Commenting the m_OSGWidget1->getManager()->redraw(); and the same in makeBox() solved the problem for me.
