My map of Italy has glitches at the exact same spots, but they look a little bit different. It seems to me that a rectangular crop from Europe has fewer glitches than maps that show just a single country. Perhaps it has also to do with polygones that have to be closed automatically?
For what it is worth, the Geofabrik extract of Finland needs some special treatment for mkgmap processing. I carefully selected the tiles so that the coastline in the south-east corner of the map ends outside the tile boundary. In the northwest, it was impractical to do this, so I had to enable extend-sea-sectors for one tile, in order to close some coastline that is outside the Finnish border. Before I moved to osm.pbf processing, I had a sed or Perl script that moved the endpoints of the coastline outside the then tile borders. That worked too, but I no longer want to use the XML, for example, by editing the osm.gz tiles from the splitter. Marko
