MNG images aren't supported. You'll need to convert this image to another format before selecting it as a background, or else use a different image.
Comment 2 Martin Seidel 2021-02-11 18:56:07 UTC 
If I change to a login screen where the default background is set (Elarun for example) it doesn't work either. I'll do a Linux reinstall the next days...
Comment 3 Martin Seidel 2021-02-12 04:50:06 UTC 
This happens if I try to change the login screen:

Comment 4 Martin Seidel 2021-02-12 04:52:18 UTC 
I reinstalled Opensuse but it's the same, also "chown -R username /home/username" and "chmod 755 -R /home/username" didn't help
Comment 5 Martin Seidel 2021-02-13 10:23:02 UTC 
it is reproducable if you change the global design to "breeze dark" (maybe only with OpenSUSE)
