Hi, We're also using OpenLayers and GeoServer/GWC generated vector tiles to display features on a map.
We recently upgraded to 2.15.0 and noticed the same gridlines around the internal edges of the vector tile. Here's an example of what we're seeing for a layer styled in OpenLayers CSS with stroke width of 3: https://www.dropbox.com/s/mdwni4fs3hegy3t/Grid_lines_1.PNG?dl=0 In this cases the internal grid is quite obvious. And here's an example of what we're seeing for a layer styled in OpenLayers CSS with stroke width of 1: https://www.dropbox.com/s/15blsn6tvz9z800/Grid_lines_3.PNG?dl=0 In this case the internal grid is faint, but still visible. To help isolate the problem we read the GeoServer vector tiles into Maputnik (Mapbox GL JS) and Leaflet. In both cases we still see the same internal grid issue. The width of the internal grid seems to be proportional to the width of the feature's outline stroke style, although this might be due to overlaps betwen the tiles obscuring the full style. To narrow down which version of GeoServer migth have introduced the issue, we stepped back through the recent releases. It looks like it was introduced in 2.14.1 as we see the issue in that release, but not in 2.14.0. In the response above Andrea provided a link to: http://vtp2018.s3-eu-west-1.amazonaws.com/vtpext-wmts.html#/ I can see the internal grid in some cases on that site - for example I see it with the "Night" SLD style: https://www.dropbox.com/s/q1grew5r7b40le2/Night_vector_tile_grid_lines.PNG?dl=0 And if I edit the Mapbox style, I can see it more clearly: https://www.dropbox.com/s/nxtla7y0w08k4by/Night_with_grids.png?dl=0 Any idea what might be going on with the internal grids?
