Just, don't waste your time with Vtk and OpenGL2. Keep the backend with OpenGL only.

When I used VTK 6.2, only the edges of faces that were visible (i.e. not culled) were shown, with VTK 7.1.0 all edges are visible, even for faces that are culled. My VTK 6.2 was compiled with rendering backend OPENGL, and 7.1.0 with OPENGL2, which is what most likely causes the difference in behavior.
