[Paraview] Toggling between 2D & 3D view Issue

[Sebastien Jourdain]

Why don't you use two truly separate view on the server side. That way you
won't have any rendering artifact. And you can easily show/hide the local
one in the web browser.
Then on the client side, you just have to worry about which one is visible.
