A guess: perhaps those Natural Earth layers contain vertices close to the poles? EPSG:3857 is valid only between -85 - 85 degrees. If that is the case it might to help to cut your vectors a bit at high and low latitudes. -Jukka Rahkonen- _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
