Bug Description

Binary package hint: unity

1. Set up a dual screen configuration
2. (optional) Set the clock to display seconds
3. (optional) Open Chromium and open on a page that will cause a notification to appear after a delay (GMail/SO Chat/GCal/etc.)
4. (optional) Schedule an application to open, or close, after a delay.
5. Lock the screen.

The Unity panels (the top horizontal panel and the vertical panel, if visible at the time of lock) will remain visible through the lock screen. The clock will update normally every second. Chrome notifications will pop up above the locked screen. None of these elements accept input, but they still leak information about what the user is doing.

Possibly bug 886605 instead. But they're essentially the same thing, I think.
