cinnamon: Errors on unlocking screen after Ctrl+Alt+L locking (sometimes)

[Butterfly1984]

Describe the bug in lock screen, when typing one character in password field, one dot is seen for the one character i typed, and entire screen gets slightly dimmed, no single keystroke works after that, screen stays in that situation till i press escape key, then when typing 1 character again for password it repeats again, clicking on the "switch user" icon brings me to login screen (where other DE can be selected), where everything works perfect again.

happened twice in 6 days, both times in the morning, i always lock my pc with Ctrl+Alt+L

i tried reproducing it, but it only happened twice, each time in the morning after PC was locked for the night

To Reproduce Steps to reproduce the behavior:

1. Lock screen with Ctrl+Alt+L
2. Wait many hours?
3. Type 1 character in password field
4. Screen goes slightly dimmed, no other keypresses work except escape key or mouse click on 'switch user' icon

Expected behavior be able to type password completely

happened a third time this morning, Additional logs: http://dpaste.com/3TW31W1 Video: https://i.imgur.com/OJLus49.mp4 (first 2 times i try typing password completely, but only one character input shows)

i've only ever connected one keyboard and mouse to this PC, the keyboard layout US, English was selected in the Mint installer and not changed later.

It's something that only happens after session was locked for at least 8 hours (or 10 hours?), cause it didn't happen every morning, it only happened some mornings (3 out of 8 mornings), the session was locked for over 12 hours this morning when this bug happened

discribe the bug: "After locking session, i need several attempts to enter the password. Mouse doesn't work, but keyboard does. When entering characters, it says it's processing and i need to press Escape key to continue, after this is can fill in password, but while i type my full password, no stars or 1 star only appears. Happened twice today while i was shopping"

reproduce: hit the lock screen key in menu go shopping come back and try the discribed above

expected behavior: mouse can promt password field insert password with stars dont need hit esc to promt the password field

frequency: always
