I have a basic layer from PostGIS of points. All of the points are rendering perfectly fine at the default zoom level:
As I zoom in, the tiles that are bottom left of the image are not being regenerated and the older tiles are being zoomed (points on the right are new tiles):
When I use Google Maps / OpenLayers to present these layers on top of a baselayer map, it appears as if they aren't even being displayed and it has the effect of looking like the points just disappear when zooming.
I don't think this is a caching issue as I've reset the cache multiple times, and this happens when I'm previewing the tiled layer from within GeoServer (eg: http://geoserver.local:8080/geoserver/gwc/demo/layer?gridSet=EPSG:4326&format=image/png). Styles also don't make a difference.
If I use the Common Formats OpenLayers link, or any of the other All Formats preview, I get all of the data as expected.
