[Paraview] Overlapping ParaView windows obscuring each other in ParaViewWeb visualizer server

[louise.davies at stfc.ac.uk]

Hello all,

I seem to be observing odd behaviour on my ParaViewWeb server, in that the server works and a client can see their visualisation window fine provided a window does not overlap the ParaView window that is spawned when the user connects to the server. If a new user connects, a new ParaView window is spawned in the exact same place as the previous one, and the first user now sees the image displayed on the second user's server - seemingly because the first user's ParaView window is underneath the new user's window.

It's not just overlapping ParaView windows either. If I connect to my server via VNC and place any window on top, it also obscures the user's view, although it just blacks out the screen and doesn't show the actual window itself to the user. Attached are some screenshots of what I'm trying to describe, showing what is happening on the server desktop and what the result is in the Visualizer window.

Any ideas on what could possibly be going wrong would be greatly appreciated.

Kind regards,

Louise Davies
