Public bug reported: When the display size changes (due to actual display size change caused by undocking, or via xrandr, for example), unity breaks. Lots of flashes (sometimes fast, sometimes slow), and gradually will corrupt. Switching to console and restarting unity will work, as will restarting lightdm.
Attaching a couple of videos of this.
