This part is working very well.<br><br></div>I built the 5.0.0 version of ParaView on our data server with the OpenGL2 backend enabled, but when I built the 5.0.0 version of ParaView on my client with OS X (I needed the developement headers), I noticed that I forgot to add the option to enable the new OpenGL backend: -DVTK_RENDERING_BACKEND=OpenGL2.
