I can always (almost always ?) trigger the bug with the following procedure:
1) copy some directory from one drive to another (must be big enough to have nautilus copy window show)
2) the cancel button (a red button on the right side) has a black square on its upper right corner

Once this has been triggered, the restart (reboot ? Redémarrer in french) button in the restart/reboot dialog has the same problem.

If the mouse pointer goes uppon the artifact, it will disappear.
