Bug: mesh.thumbnail hangs in docker container #1086

I cannot run a pipeline in a docker container that takes a screenshot of the mesh.

Have you started the xvffb? https://vedo.embl.es/autodocs/content/vedo/vedo/settings.html#Settings.start_xvfb

starting xvfb (can take a minute) .../usr/bin/Xvfb
 xvfb started.

It looks like running it in VSCode in debug mode doesn't work because set_xvfb.sh does not store the information in the debugger when it's run as a prelaunch task

to be honest I'm not familiar enough with the xvbf machinery ... :(
