Bug Description
When system returns from suspend mode, user is not prompted for password, so last thing that was active before suspending is visible, but clicking around does not work. Only thing that is clickable is top menu (network, sound, battery icons) but menu only opens and clicking further options is not possible. After that, I lock screen (win key + L) and main menu (with launch pad) is visible, clickable but anything I click is not visible while screen is locked (later, when I unlock screen, those app that I clicked are open). After unlocking screen, everything works normally.
Suspend is initiated using keyboard
This was not case before, but suddenly it started to behave like this, I don't know why, I don't remember installing anything.

I expected lock screen when system returns from suspend mode

Additional (maybe) useful info :
I remember that this bug started to happen when I started to use HDMI cable. Sometimes I suspend system while cable is still inside, and remove it while system is suspended.
