[mkgmap-dev] Colouring of island not correct

Hi! I tried to generate a gmapsupp.img with mkgmap. I have done this with: /usr/java/jdk1.8.0_144/bin/java -Xmx8G -jar ./mkgmap-r3993/mkgmap.jar -- gmapsupp karten/corse-latest.osm.pbf But the colouring of the landscape is not correct. See "corse_wrong_colour.png" Compared to "bremen_correct.png" Screenshots are made from qlandkartegt Version 1.8.1. I also tried to use "--precomp-sea=./karten/sea.zip", but this just colours the surrounding sea. Do you have any ideas? Thank you Best Regards Christoph
