Description

Hi, this issue may be somehow related to #13862.

This compley polygon with "cut outs" will only be displayed on screen is it does entirely fit the screen. If the focus is moved in a way that the polygon is partially moved over the screens borders, it will not be displayed anymore.

Attached 2 screenshots + the shp-files.

Many thanks for solving this issue!

this polygon has a nasty error,
if trying to import it in postgis I get

Creation error for features from #0 to #0. Provider errors was:
PostGIS error while adding features: ERROR: Polygon must have closed rings
CONTEXT: SQL function "st_geomfromwkb" statement 1

if you clean it, for example with the st_makevalid function with the

http://plugins.qgis.org/plugins/processinglwgeomprovider/

plugin, you get a vector without this issue.
