password prompt hangs then screen corruption

[Ken Pratt]

Binary package hint: xscreensaver

After an xscreensave lock after timeout, entering the wrong password causes about a 1 minute hang followed by the password box jumping down the screen and showing nothing but white. The mouse pointer is the busy pointer. After some time and clicking around, the white box jumped up to the top portion of the screen and the login box appeared below it. I was then able to log in. I did switch to a virtual console (CTRL-ALT-F1) and back to X prior to entering the correct password. I also have thinkfinger installed.

I can not reproduce this behavior by manually locking the screen.
