SDDM login screen no longer showing users with faces?

Hi all, is it just me or did the SDDM login screen recently stop displaying the list of users with their pictures/faces? I only have username/password prompt, that at least seems to remember the last user. But the pictures of the local users are gone. Not sure when this started, if memory serves last week. Maybe with the big Plasma6 upgrade? I deleted the empty /etc/sddm.conf and moved an old (?) file from /etc/sddm.conf.d/, but no change. Kind Regards Johannes
