points disappearing on zoom

[anthony farrant]

No the layer state is good since it shows some of the points.

To be precise I'm mapping Antarctica. When I zoom on Antarctica, the
region directly on the coast of Antarctica is devoid of points (which
should be there, since they were there on the first drawing) while on
the periphery there are still points. So it's shows the layer "on the
periphery of the zoom but not in the middle." When I pan or zoom
closer on a specific region the points reappear. So basically it's a
one unique level of zooming that part of the points disappear...

Does this make any sense? It's quite frustrating.
