I haven't seen this particular issue, but I have had a whole bunch of strange, likely firmware-related issues on my Retina.
For instance, sometimes the screen just won't shut off when trying to put it to sleep - Closing the lid and the screen/logo stay lit up indefinitely. Chrome and the integrated graphics card really don't play well together - it's caused an OS reboot 10's of times in the past month. Mostly, waking the computer from sleep takes a fraction of a second but sometimes it takes ~20 seconds to show the screen.
I would guess that all of these are related to the integrated Intel graphics chip firmware/drivers being not quite baked.
BUT - in spite of all of that, this is without question the best laptop I've ever owned. It's also the first laptop where I haven't wanted or needed to use my iMac anymore. It really is finally a true "desktop replacement" that is totally portable. And I could never go back.
