screen recording

When I fullscreen an image opened in Gwenview or other image viewer apps, it sometimes moves to the primary screen, but only the first time it's fullscreened. This started to happen recently.

See the attached video.

Does this still happen for you in Plasma 6.4.5?

If so, please attach the output of kscreen-doctor -o

No, I can't reproduce this bug in 6.4.5. Seems to be fixed.
