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.

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.
