It's kind of hard to describe it precisely, so I made a video.  :)

It only affects X, not the console, and it seems to go away if you log
out back to the login manager (I'm using GDM on Fedora 20) and back into
your window manager.

I've tested with OpenBox, Gnome and KDE, and it happens in all three, so
it doesn't appear to be related to the window manager.

It does appear to flicker more if you move the mouse, but it still does
flicker occasionally if you aren't doing anything.
