ParaView does not render surface plots of cell data #110
Description
While upgrading to Ubuntu 26.04 (with lightdm and an Xfce environment, as described in the install-basics.sh), ParaView does not seem to render surface plots of cell data.
It works just fine with "surface with edges" of cell data, as well as with surface plots of point data.

While ParaView is installed as apt install --no-install-recommends paraview, the --no-install-recommends does not seem to play any role here.
On another normal desktop Ubuntu 26.04 installation, with GNOME, everything works.
