Hello Guys,
I am brewing custom maps for my Garmin zumo 396.
- get the OSM data from the overpass api (0.5 by 0.5 degree
counding box)
- use splitter to split too large parts
- use mkgmap to build the maps.
The generated garmin maps have wrong filled polygons, lakes are
filled with land and vice versa.
Here are two examples (lake Balatom and lake Geneva)

When I download the lake Balaton in one bounding box the
artefacts are disappearing, thus there must be something merging
the files.
I have tried various mkgmap settings but could not solve the
issues. Curret config is:
levels: 0:24, 1:22, 2:20, 3:18, 4:16, 5:14, 6:12, 7:10

Do you have any ideas what can cause the issue?
