Mapcache rendering issues
Following tile has a row of transparent pixels 1 pixel wide on top, right and bottom of the tile. https://emg.pass.copernicus.eu/cache/ows/wmts?layer=Emergency__TRUE_COLOR&style=default&tilematrixset=WGS84&Service=WMTS&Request=GetTile&Version=1.0.0&Format=image%2Fpng&TileMatrix=13&TileCol=9392&TileRow=2298&time=2020-01-24T09%3A26%3A34Z%2F2020-01-24T09%3A26%3A43Z This produces unpleasant artifacts while viewing the layer in client. It was confirmed on other collections as well, but only for new tiles, therefore I suspect mapcache update to 1.10 to be culprit, as there have not been any other cache/renderer related updates on production machines since then?
Not sure how to fix this. @fabian.schindler says, that this problem was already observed before on NDVI rendering.
