Screenshot
It looks like the screenlocker's surface becomes resized for a split second, not covering the whole screen anymore and the content beneath it is revealed. Created attachment 151008 [details]
Screenshot 2
Here's another sample, where no content is revealed though.

Screenrecording
A very last example: Screen recording related to attachment "Frame by Frame".
Side node: When I finally unlocked the screen, all windows were moved to B and C showed the desktop of disabled screen A (wallpaper + widget), which was scaled down in the upper left corner, covering ~2/3 of B's screen. This issue went away after several seconds, before I could take a screenshot. > ~2/3 of B's screen.
I meant "~2/3 of C's screen."
