Hi Peter @PFavinger ,
Hard to tell, this definitely doesn’t look right (looks more like it Baked the Displacement from Level 1 to Level 0, or so).
It’s not because of your UV’s and probably also not becauise of the Blender Version.
Could you provide a link to your .blend file (uload to Dropbox, Googledrive, or so and post the link here) please? That’ll help troubleshooting.
