Describe the bug
I am trying to reproject a raster image from epsg:4326 projection to epsg:2056 the swiss coordinate system in QGIS.
The result is a raster with 150m misplacement in diagonal direction (around 15 pixels). Doing the same reprojection with gdal brings no problems.

Expected behavior
I compare the result with a vector layer. The raster is well georeferenced in epsg:4326 but not in target projection.
