I've seen that happen with Macbooks for years (the rainbow static), with both my mid 2012 retina MBP and the pre-retina one it replaced. Happens occasionally with my Dell monitor at home, and would happen with one of those knockoff IPS' that I used at my previous job pretty frequently. Unplugging and replugging the monitor will eventually fix it, but yeah, it's obnoxious.
