The issue happens iff I use two screens on my Lubuntu machine
simultaneously. Then vtk_pipeline->get_screen_size returns zero-sized
screen from some reason. On colleague's Ubuntu machine same DOLFIN and
VTK (on remote machine) works well.
Hence this issue is probably caused by poor integration of multiple
screens in LXDE desktop and/or an interaction with VTK, X11.
>From this reason, default value of
VTKPlotter::parameters["tile_windows"]
could be set to false. I don't care a much - what do you think?
