I am using Natural Earth coastline polygon (NE_10m_land), loaded from a shapefile in QGIS. All displays well (in, e.g., unprojected WGS84, EPSG 4326) - see below:

enter image description here But when visualising in a polar projection (here, EPSG:3571, WGS84 in a North Pole LAEA Bering Sea projection), QGIS seems to lose the ability to distinguish between the inside and outside of polygons.

This does not seem to be a problem with the shapefile ( not well formed polygons) as I can visualize it using ArcGIS just fine.

enter image description here So this seems to be a problem with the rendering engine in QGIS. Any hints?

Edit: It appears that it is indeed caused by Antarctica. Manual removal of Souther Hemisphere helps.

EPSG:3571 without Southern Hemisphere landmass

    I think that is Antarctica - try deleting the southern hemisphere – Ian Turton Jun 14 '18 at 8:05
  • Thank, will try. Funny it displays correctly in ArcGIS. I lodged a bug issue here too (no action s ofar): issues.qgis.org/issues/19191 – MartinT Jun 20 '18 at 4:16

This issue seems to be caused by Antarctica. Hope the edit above helps someone. Yet, not a very nice behaviour from a user perspective, but understandable.
