So far appearing only with data that have overviews (Element84) and zoom level higher or equal to 10

The tiles appear to have transparency on the sides as opposed to WMS which fully covers the area WMTS: WMTS https://data-access.192.168.49.2.nip.io/cache/ows/wmts?layer=S2L2A__TRUE_COLOR&style=default&tilematrixset=WGS84&Service=WMTS&Request=GetTile&Version=1.0.0&Format=image/png&TileMatrix=16&TileCol=71503&TileRow=15208&time=2019-09-04T21:45:57Z/2019-09-13T20:23:59Z WMS: WMS https://data-access.192.168.49.2.nip.io/ows?request=getMap&service=wms&version=1.3.0&layers=S2L2A__TRUE_COLOR&width=256&height=256&format=image/png&time=2019-09-08T00:00:01Z/2019-09-10T00:00:00Z&crs=EPSG:4326&BBOX=48.22723388671876,16.38885498046872,48.22998046875001,16.39160156249997

workaround found, setting:

<metabuffer>1</metabuffer>

Some notes:

  • metabuffer makes 258x258 requests which don't have gaps.
  • changing grid zoom levels makes different sets of gaps appear at different locations.

Workaround for vs/client serving WMS layers with special rendering (other than default layer) is setting gutter parameter > 0.
