I get snow like old TVs, just momentarily. Let's call it 600msec.

I have the exact same problem with my 2016 Retina MBP...

Got the same behavior with 10.13.1 upon wake from sleep or simply by putting display to sleep and on again.

Got a picture of the boot apple with the progress bar in weird colors for a brief moment.
