After resuming from suspend via lid closure, the full desktop flashes briefly. Following this, if the super (Windows) key is pressed, the dash menu appears (but is not clickable), revealing the launcher and allowing the user to see which programs are running on the system.
This does not occur during regular lockdown (power->lock screen) but only when the system is suspended and locked via the lid close event.

Can you still reproduce this with all the updates as of today? A lot of fixes for screen locking issues went into Oneiric in the past few days.
