I have mac mini with two monitors and sometimes when I wake it from sleep I get this weird screen:
This is a normal screen:
This isn't a big issue (at least I hope so) as it goes back to normal after clicking cancel and waking up again but still wonder why this happens.
This might be better asked on Ask Different. – AStopher – 2015-05-11T10:27:03.160
I think it's just a hardware bug with Macs. Someone had the same problem on a Mac, but with Ubuntu, pointing to it being hardware. – TheWanderer – 2015-05-11T12:48:49.653

I have a 13" Retina MBP bought 2016. But this problem has only started happening occaisionally in the couple of months - since Xmas 2016. I was wondering if it had anything to do with updating to Sierra. – Annabel – 2017-02-13T18:28:22.173
