I can reproduce in Gnome with both gnome-screensaver and xscreensaver
when opening firefox or gnome-terminal menus.

xscreensaver reported the following lines when the timeout expired:
xscreensaver: 20:16:02: couldn't grab keyboard!  (AlreadyGrabbed)
xscreensaver: 20:16:06: couldn't grab keyboard!  (AlreadyGrabbed)
xscreensaver: 20:16:10: couldn't grab pointer!  (AlreadyGrabbed)
xscreensaver: 20:16:10: unable to grab keyboard or mouse!  Blanking aborted.
But I don't know much about all this...
