Login / switch user passwords visible on screen!

Bug description:
I suspect many of the details I'm providing in this bug report are
irrelevant, but as I don't know exactly what is causing this issue I'm
trying to provide more information rather than less.
I recently installed Ubuntu 18.04.1 on two relatively old computers
(mentioning their age because the installer may have chosen to
configure them differently based on their hardware). Ubuntu was
installed on an unencrypted partition next to Windows (Windows 7 on
one computers, Windows 10 on the other).
After doing this, I added two additional non-admin users through the
Users control panel, in addition to the admin user that was created
when Ubuntu was installed.
After doing this, I was regularly using "Switch User" to switch
between the various user accounts. Whenever I selected the "Switch
User menu command, before the graphical user-switching screen came up,
I briefly saw a screen with some kernel messages on it, and BELOW THE
KERNEL MESSAGES WERE THE PASSWORDS THAT HAD BEEN USED TO LOG INTO THE
VARIOUS ACCOUNTS, visible right there in plaintext.
I am not sure whether these passwords were printed as a result of an
initial login, a "Switch User", or both. All I can tell you is that I
was able to see other users' passwords briefly whenever I executed the
"Switch User" menu command.
I am not able to reproduce this on a third laptop. On this laptop,
when I execute "Switch User", the screen goes blank briefly, rather
than showing a screen with kernel messages and passwords on it. I
wonder if this has something to do with the graphics card or
capabilities or something.
I have attached a photo of what I saw before the user-switching screen
came up, with the passwords blurred out of course.
Please let me know if there's any other information I can gather to
make this report more useful.
