Which is true - xagoagent/nxagent still does not support XInput2. It
is on the software you use if it can deal with Xinput1 or not.

But from my experience these messages are informational, not show-stoppers.

IIRC paraview is a 3d application so these issues might be related to
you graphics drivers, too.

In https://discourse.paraview.org/t/running-paraview-in-virtual-machine/2624
and https://wiki.classe.cornell.edu/Computing/ParaView I found
paraview-mesa being mentioned, does it work with this wrapper? Or
maybe with paraview --mesa-llvm?
