Sorry, didn't notice this bug go past. I can't think of anything that would have changed in LightDM and the log isn't showing anything going wrong. I was going to suggest you try downgrading LightDM but you've done that. My best guess is the session / light-locker haven't realised they've been unlocked for some reason? Either that or something to do with VT switching (driver issues?).
