Problems with user login and recovery from lock after upgrade

After upgrading 3 machines from Fedora 19 to 20 I noticed some odd behavior. First, the screen shield would kick in even if no user was logged in. Second, after hitting escape to clear the shield I the username field was grey. Clickig into the field, I'd have to hit enter twice to get the name entered to "take". Finally, after clearing the screen shield for a logged in user the system would hang after I entered the password and bounce me back to the screen shield

I have not seen this problem in any of the (many) systems I've done a clean install of Fedora 20 on.

Note that I am using the 01-local-settings file method to suppress the user login list (discussed in https://ask.fedoraproject.org/en/question/9875/how-do-i-disable-user-list-in-gdm/ ).

Had some time to experiment more with this today and found that new, clean user accounts didn't appear to experience the problem. Guessed that it might have something to do with my pre-upgrade user profiles so I backed up the existing home directories and then re-created from scratch, copying over everything (including dotfiles) that were not Gnome related (including .config, .local, .gnome, .gnome2, etc).

UPDATE:

Everything seemed good for a few days but then the problem resurfaced. I am now experimenting with "screen lock" turned off for the gdm user (launched gnome-control-center as gdm and then configured in Settings... Privacy).

ANOTHER UPDATE:

Turning off gdm's Screen Lock didn't do the job, but turning off Blank Screen (Power... Blank Screen... "None") did. Of course with my monitor that means that if no one is logged in the screen doesn't blank... ever. Pretty clearly there's a bad interaction between something in my config and Gnome screen-blanking, but getting at the root problem in a subsystem as historically problemmatic as the Gnome login is beyond me.
