Hi Torben, The implications of setting `global: true` are that OpenLayers assumes the projection extent to span the world from -180° to +180° longitude. Both potential fixes you linked will cause unexpected results for projections whose validity extent does not span the globe in longitudinal direction.
One approach that could work is that you try to reproject the projection validity extent to EPSG:4326 and see if the reprojected extent goes from -180 to +180 in x direction. But there will also be pitfalls with this for e.g. polar projections. My recommendation would be to not consider the current behaviour a bug, and make the GeoServer preview not wrap the globe at all. Instead, configure the map's view with the projection's validity extent, so the map center will always be within the validity extent. I hope this helps. Andreas.
