I'm also experiencing this issue. To test for the issue, I just open a
file in vim (I used /etc/courier/imapd), maximize the terminal, then
page-down till you hit the end of file (but no extra page downs or it
will refresh). Naturally, you can also just use the terminal for 10
minutes and you'll see the issue all over the place.
I can also confirm that this is a problem when using the NVidia
proprietary drivers. The issue goes away when you remove the drivers and
fall back on Nouveau (As the bugreport Gregory Gleason referred to
points out).
I find gnome-shell causes audio stutters and lag when using Nouveau,
which is why I prefer to use the NVidia drivers.
