Looks to me like it is rendering each way as a polygon, ie: drawing the way
as a line then connecting the first and last points together and trying to
fill the bits inbetween. This looks more weird in some places than others
depending on the shape of the coastline and the length of the ways. I don't
think there's anything wrong with the actual data.
