I now have a second system with this problem. It's my laptop and it's
been re-booted (several times) and I have re-build both polkit and
policykit. 

No change in behavior. Every time a character is entered, the screen
starts to draw the background for the screensaver, but immediately
blanks again. (I use the Blank screensaver.)

Any additional information I can provide?
