As soon as I set the threshold to 0 the warning about the OpenGL 3.2 context

No segfault just means that the scene didn't attempt to rendering
something that needed newer OpenGL.
I tried a very minimal example that creates a 3.2 context (using SDL) and
that fails as well, so maybe something strange is going in with our nvidia
driver installation. I'll see if I can do some more tests.
Cool. Thanks.
I did some further testing, but can't find anything obviously wrong with
our setup w.r.t OpenGL versions. I do notice that window setup in SDL2
fails due to the XRandR support finding no outputs configured on the
graphics cards (there's nothing connected as these are cluster nodes).
GLFW3 reports "X11: RandR monitor support seems broken", but initializes
and renders (on :0.0) anyway when requesting a 3.2 context. Does
ParaView, or VTK, use XRandR to get a valid window on which an OpenGL
context is created? Could this be a reason I see the 3.2 context
creation failure?
Regards,
Paul
