Bug Description
I have marked this bug against Unity but may be incorrect.
When a Youtube video is fullscreen and left until the lockscreen activates (set at: screen off after 10 minutes, lock after 30, require pwd), on returning to the PC, possibly hours later, the now-ended video image is displayed but no mouse operations are possible.
In fact, the lock screen has activated but failed to become uppermost, ie, it has popped under; the screen is locked but that cannot be seen.
At this point, to recover operation: hit enter (to clear the password 'buffer' if any keys have been pressed); type the password and hit enter; the mouse is now operational on the Youtube screen, so click the YouTube lower right minimise button (or press escape).
This is a security vulnerabilty, as the last full-screen image displayed before lock activation remains visible. Until proven otherwise, the impact may not be restricted to YouTube.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
