[Geoserver-users] GWC rendering issues with point layers

Hi, with default settings with GWC (v 2.3.4) , I have a rendering issue with point layers. As shown in the screenshot ( http://kongs2.medisin.ntnu.no/tiles.png ), GWC does not render the complete shapes of points that intersect 2 lines. Any way to fix this?

This happens because GeoServer cannot predict how big the circles will
become.
In GWC setup a gutter large enough to capture the radius of biggest
possible circle, in WMS add &buffer=x where
x is again the size, in pixels, of the radius of largest possible circle
