Strange lines when zoomed in

[Stephen Lime]

The *only* way to get that artifact is by drawing line shapefiles as polygon/polyline layers.
There are no polyline shapefiles.

Yup, I've seen that just change the type from POLYLINE to LINE and that
problem will go away.

I'm not sure the logic behind that though, since I had the same problem with
rivers doing that, even though
they ARE polylines, I have to set them as LINES to avoid it.
