Description

I get the tile-offsets as shown in the attachment when particular imagery layers are reprojected.

How to reproduce:
Set Mercator/EPSG:3857, load Berlin 2011.

Tiles are shifted, retrieved as epsg 4326:

2017-11-20 11:17:56.652 INFO: GET http://fbinter.stadt-berlin.de/fb/wms/senstadt/k_luftbild2011_20?FORMAT=image/png&VERSION=1.1.1&SERVICE=WMS&REQUEST=GetMap&LAYERS=0&STYLES=&SRS=EPSG:4326&WIDTH=512&HEIGHT=512&BBOX=13.3717263,52.4665849,13.3730996,52.4679582 -> 200

When I switch JOSM to epsg:25833, it retrieves the images again in native projection and displays them fine.

I had tried to clear the cache for this layer, but behaviour remains.

Set Mercator/EPSG:3857, load Berlin 2013, which does not show the problem:
However JOSM retrieves Epsg 25832:

Well, it might be the case that the fault comes from the server when delivering epsg 4326. If that is the case, I'd need a method to nail the imagery layer to be retrieved in their native format (e.g. always 25833)
