Missing Data in 3D Connectivity Visualization

It looks like under the hood we use pyvista.Line and add a mesh:

mne-tools/mne-python/blob/926bec285c34c0fbdcad7b09ac4f550af8288e8a/mne/viz/backends/_pyvista.py#L607-L625


      
          for pointa, pointb in zip(origin, destination):
              line = Line(pointa, pointb)
              if scalars is not None:
                  line.point_data["scalars"] = scalars[0, :]
                  scalars = "scalars"
                  color = None
              else:
                  scalars = None
              tube = line.tube(radius, n_sides=self.tube_n_sides)
              actor = _add_mesh(
                  plotter=self.plotter,
                  mesh=tube,
                  scalars=scalars,
                  flip_scalars=reverse_lut,
                  rng=[vmin, vmax],
                  color=color,
                  show_scalar_bar=False,
                  cmap=cmap,
                  smooth_shading=self.smooth_shading,

So you could look into the relevant PyVista objects and see how they can be modified…
