More specifically: if I prefer to turn off the screen after one minute, 
when the screen is locked, then the screen goes to blackness immediately 
(not after one minute) and the wallpaper does not appear until it's time 
to unlock. Then if I do nothing, the wallpaper persists for a minute 
before blackness recurs.

Not reproducible with Kubuntu 25.10 on real hardware. A moment of 
blackness is followed by appearance of the wallpaper, and then the 
wallpaper persists for a minute before blackness recurs.

With an assumption that it's fixed upstream: I'll not make a separate 
report in Bugzilla for FreeBSD.
