                                  I can't remember which mode, tile or
                                  cave, doesn't support tile and

                                  <br>
                                </div>
                                <div>You should aim for tile mode then.
                                  You can enforce and thus correct the

                                              I am using ParaView in

                                              background over my 8
                                              screens. The background is
                                              displayed on each screen.
                                              3D models are well
