  On openstreetmap.org the boundary of Lac-des-seize-iles does not render correctly (there is a line across the lake that should not be there) But I looked at the relations and cannot find anything wrong with them. Sounds like a rendering engine bug more than a mapping error. If somebody find the solution would be nice.
