I wonder how common this is. It certainly raises some questions as to copyright issues. Has anyone else had this happen? This is a KPDM_2 generation presented as-is, based on an 0.6 image-to-image (from a 3D rendering of my own which does not contain a watermark). Out of hundreds of images I've generated, this is the only one I've seen that shows a mark.
[EDIT]: A similar mark showed up in almost the same spot in another generation! https://ibb.co/ssnSDr4
