This rings some distant bells, though not with that particular EPSG (I'm in antipodes). I have vague memory of needing to set a tile origin somewhere. First step would be to isolate whether your issue is with geoserver or the browser client. (my memories of this are with openlayers but I switched to leaflet some time ago). Can you look at the getmap request that browser is issuing and see whether the image being sent matches the bbox being requested. If so, then geoserver is off the hook and the problem is with the tileset management in the browser client. If it doesn't match, then problem is with geoserver. You say "cached content" - are you explicitly connected to a GWC cache or tileset, or is this from integrated GWC where you have seeded tiles? If you turn caching off, does the problem persist?

Please see the attached screenshot. It doesn't do this in web Mercator projection. If you try to zoom in using this gridset the you end up in a completely different point (because the map centre is shifting) whilst if you scroll in on other projections the map centre remains constant. It seems to have a minimal shift if I use the WMTS in QGIS but if I use it in MapInfo Confirm then the shift is more pronounced.
