The blue square is originating from the data in the shoreline_300.shp
file. Can you confirm the timestamp on that file? The latest one[1]
should have a date of 2011-06-05 and I think it is free of this problem.

The squares indicate an areas of the map where the coastline data is
sufficiently broken that is has confused the algorithm which generates
these shapefiles.
