My external display just started going to rainbow static and back over and over again. Didn't think to blame the update till now. Also just had my first kernel panic in about a year.

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.

Since installing 10.9.3, every time I wake my rMBP (mid-2012) up from sleep in the morning I get a full screen of static for 4-5 seconds. Subsequent attempts to reproduce fail, but the next morning it happens again. http://i.imgur.com/5dHFgN6.jpg http://i.imgur.com/5dHFgN6.jpg I also hadn't thought to blame the update for this until now (as I just have lost all faith in this particular model) but the timeline matches up well. Edit: after re-reading, I think I know what you're referring to about the random static on the external display, which I've experienced over HDMI and Apple hasn't been able to debug (support case open for more than a few months now).
