[Paraview] Error when connecting to pvserver (pv 4.3.1)

[Utkarsh Ayachit]

Which vnc server are you using? Seems to me your VNC server is missing
some X extensions (or something like that). We do use VNC servers here
for running tests, so it's known to work.

Only if I run the ParaView client from within a VNC session the observed problems occur. Any idea where I might look for a possible solution? Using ParaView via X forwarding is unbearably slow in my current setup…
