Hi,

I noticed an offset of about 20cm when serving the ImageMosaic data as WMS and WMTS.
The raster file is in EPSG:31466 on the file system.
When publishing the ImageMosaic, the native coordinate system was correctly set to EPSG:31466.
Declared SRS: EPSG:3857
SRS handling: Reproject native to declared
Everything else was left at default settings. In the “Tile Caching” tab, only the GridSet EPSG:3857 was added, which is a completely identical copy of EPSG:900913.

I have attached two zip files, one containing my complete workspace from GeoServer and another containing an example raster tile.
If I add the layer as WMS and WMTS in QGIS, the offset of about 20cm is clearly visible (see screenshot).
