    So I've just noticed something interesting on my recently aquired 2015 15" Pro.
    I might just be paranoid but I want to hear if this might be a symptom of something undesireable.

    When I open the machine, waking it from hibernation, the screen is all messed up for a fraction of a second.
    I found an image online that illustrates precisely what my screen looks like:

    Keep in mind that it is only like this for the teeny tiniest moment before becoming normal again and I never experience anything similar at any other point while using the machine.

    I'm using a scaled resolution of 1680x1050, if that's relevant.


    So, am I being paranoid or could this be something?

    I too hope not. Planning to get this one. Get it checked asap. If its a logic board issue again, return it

    Problem is, there are no Apple Stores in Norway.
    So I can't have it checked out, might have to call them.

    Does this persist if you were to use the native resolution and wake the computer from sleep?

    I'm experimenting right now with repeating the glitch on demand.
    The biggest problem is letting the Mac sleep long enough, I've only noticed it thrice now.
    All instances of the glitch have occurred after longer periods of closed lid sleep:
    Yesterday after several hours, this morning after a night og sleep and today after work.

    I'll first try running with the default resolution, then I'll try reinstalling OS X, should the problem persist I might be forced to contact Apple.

    I ended up tampering with the power management settings (pmset) to make the Macbook enter Standby Mode faster.
    And after some testing with scaled resolutions and standard settings, it seems like the glitch only occurs while using scaled resolutions (1680x1050 specifically, I haven't tried the other settings yet).

    This might not be a problem after all.
    Could be a driver issue perhaps?

    EDIT:

    Further testing seems to prove that this definitely is an issue with scaled resolutions.
    Adjusting the slider above 1440x900 makes the screen spaz out upon waking from Standby Mode.
    So 1680X1050 and 1920x1200 results in a booboo.
    1026x640, 1280x800 and 1440x900 work fine.

    It's more than likely just an issue with Retina displays and Yosemite.

    Yeah I'm going to let this one pass, doesn't seem like a potential hardware problem.

    I get this when i wake my MBP from sleep by opening the lid after it was put to sleep connected to an external display. lasts for 0.1 seconds, i really don't think it's anything to worry about.
