The shared border may be represented slightly differently by the two polygons, so that narrow overlaps or gaps appear along the border. If it would be enough to adjust the polygons to agree about shared borders, then you can use a BorderSnapOperator instead.

Even if the shared border is represented exactly the same by the two polygons, it will be impossible to visualize the polygons with for a dashed line, since the dashes around adjacent polygons cannot be synchronized. Along the shared border, the dashes of one polygon may cover the gaps of the other polygon, making the border look like a solid line. Similar problems occur with other line styles, and with solid lines that should be semi-transparent.

Although labels with polygon attributes can be placed along the borders, it is impossible to synchronize the labels of adjacent polygons. For example, along the French-German border you can write "France" on the west side and "Germany" on the east side, but you cannot make the two labels appear opposite each other, as is often desirable.
