Thanks, it helped me. Very small mesh elements are still disordered but
oweral solution looks better.

I looked up the VTU format when I wrote the original answer, and it
turns out that we only use 32-bit floating point numbe
PS: In a moment I checked documentation for write_vtk. And there is
suggestion to use VTU, so I will try to check also this case.

Yes, it looked like not enough precision of numbers and thats why it
quantisizing mesh to grid.
I am using VTK and standard workflow from step-6:
DataOut data_out;
data_out.attach_dof_handler(dof_handler);
data_out.add_data_vector(solution, "solution");
data_out.build_patches();

Sorry, if my question(and english language) is not clear enough.
Yes those "triangles" mesh are what I call "disordered mesh". By design, my
mesh generator produces only quadrangular elements(with area nearly 1e-10),
but after few refinments in deal.ii paraview shows those pictures: one
