This happened to me once on a two monitor desktop.
I also have the two lock bug, and it happened after I had already unlocked the first lock. i.e. I entered my password, had a brief glance of my desktop and then got the lock again (normal), but the lock didn't show the dots when I tried to type my password.
Today I had a related instance of the prompt on the left not taking the input but the prompt on the right taking it.
