Hi,
When crossing the equator, 0 or 180 degrees, you will always have difficulty reprojecting shapes on the fly. That is what you are doing. Your project is in polar but you are creating a grid in WGS84.
That grid is being reprojected on the polar project. That will always happen when you try mix a more "global" CRS and a "local" projection.
Make sure everything is in the same CRS. (Save as.. change CRS).
Do not reprojection anything including the grids in the map composer.
If that does not work, you could always create the grid that you need (You may need to densify the shape). Save it in the correct CRS. You could then probably add a transparent grid in the map composer. This way, you would get the coordinates around the map but not the problems with the grid.
Hope this helps.

Hi Nicolas,The problem is not so much with the grid as that displays fine. The issue crops up with the map composer, and even with the grid as WGS-84 the same problem persists. Looked at both North and South polar views and the 180 graticule is always missing irrespective of the increment used. The latitude lines do not change and are clear line segments; these should be smoother.Data that are in UTM and with WGS-84 graticules look fine (smooth latitude lines). Is there an issue with Polar views and graticules?LesterOn 1 June 2016 at 11:41, Nicolas Cadieux <nicolas.cadieux@archeotec.ca> wrote:Hi,
Try saving the layer in WGS-84. Then make sure the project is also in the same projection. It can help sometimes to make a spatial index.
Keep me posted.Nicolas

I had some Antarctic polar stereographic data and when applying a
WGS-84 long-lat grid in map composer it generated most of the
longitude lines (180 missing), and very crude latitude lines (clearly
visible straight line segments).
Is there any way to improve the latitude lines?
