Comment (by Algunenano):

 I've loaded the dataset into CartoVL (based on MapboxGL) and there are
 some issues (lines across the polygons) in certain places, but when loaded
 individually in QGIS the tiles are ok. They are also ok when analyzed
 individually under node-mapnik.

 I'm inclined to think this could be a problem during the stitching of the
 polygons (there is nothing in the spec/format to make that easier) but I'm
 not 100% certain about it and right now I don't have an easy way to test
 with other renderers.
