OpenStreetMap 開放街圖
Yesterday I changed the tagging of several lakes and rivers around and including Lake Skutari from natural=coastline to natural=water or natural=riverbank. Today the Osmarender layer in the map shows most of the area around these lakes and rivers as water, see osm.org/go/xefe49?layers=0B00FTF
I can find no leftover coastline objects with josm search, and I checked again my lake/riverbank areas and find they are closed, non-self-overlapping ways. Any ideas what else to look for?

I haven't checked exactly, but maybe is the lake too complicated for Osmarender? If I remember correctly, "coastline" is used to split up very long ways but still be able to render large lakes or similar. From what I can tell, the lake you pointed out looks very complicated, maybe that's the reason?

according to the map features pages, coastline should not be used for lakes; however, it is quite frequently done for large lakes. I have now reduced the complexity of the shore line a bit (down to 1022 nodes from 1176) by removing the triangular artefacts that the PGS importer likes to create. Lets see if that helps.

By removing redundant nodes (nodes in the middle of an apparently straight line) I'm now down to 964 nodes. I have seen other lakes of comparable number of shoreline nodes that are rendered ok, so maybe that will work.
