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

[Schlottke, Michael]

Thanks for the hint, this seems to resolve my issue: I use tightvnc-1.3.9-110.1.x86_64 on the machine where it does not work, but on a different machine (with tightvnc-1.3.10-14.2.1.x86_64 installed) it works.

Might not be just the vnc server version but maybe a related package, but it was definitely a fault with our site setup. Thanks for helping me to track this down!

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…
