New directories are appearing in Home

My Tumbleweed behaves strangely.

alex@linux-1fj7:~> cat /etc/*-release
NAME="openSUSE Tumbleweed"
# VERSION="20190219"

After each reboot, new directories appear in “~/” :

alex@linux-1fj7:~> ls -d -1 ~/*/

Please tell me how to solve this small puzzle?

alex@linux-1fj7:~/dU/.local/share/sddm> ls

There is a previous thread on this:

Random folders in /Home (New install)

The summary: It was a bug in sddm. It has been fixed, but you might not yet have the fix so run “zypper dup” as root to update your system.
