Screen content is visible for some seconds after sleep/hibernate before locked screen

[Marius B. Kotsbak]

Binary package hint: gnome-power-manager

After sleeping the latop, I expect to get stright to locked screen mode after waking it up again. Instead the screen content is visible, possible revealing things other people should not see.
