I updated my system (Fedora 42) 2 days ago.

Since then, I have two symptoms of a bug in kscreenlocker 

1/messages in the journal

(each time I want to unlock)

2/ the photo on the screen is not round anymore, but rectangular 

STEPS TO REPRODUCE

OBSERVED RESULT

Rectangular photo + message in the journal

EXPECTED RESULT
Round photo / no message

This bug is not the same as bug 506316. 

The screen is unlocked.

Except of the rectangulard picture and th message, the behavior is correct.
