Just one more thing David, did you try also running the example
without any argument on this machine? (That would make it use a
regular vtkRenderWindow/vtkRenderWindowInteractor). It would be
interesting to know if the volume shows up then. That would confirm
that the machine can show volumes using VTK 8+OpenGL2 backend, just
not with QVTKOpenGLWidget, so would strengthen my theory that it has
something to do with the new QVTKOpenGLWidget.
