    Just got my screen replaced by Apple under the quality program and has been a little over a month. Just saw some stupid rainbow circles on my lock screen, when I wake my Macbook from sleep. Have attached a couple of screenshots I took with my phone. Circles appear once every 15 wake-ups.

    Any idea what this could be? Just read somewhere that a PRAM reset fixed it for a guy so I have done that for now. Lets hope that it fixes it.

    Sounds like software more than hardware issue.

    I think so as well. Because the mouse pointer has no distortion. But what makes me believe that it is a hardware issue is when I take a screenshot with the circles on the screen - there are no circles on the picture.

    Dont know what to do.
    The PRAM reset apparently didn't fix it.

    If nothing changed, and the issue you describe is very unusual and unique to your computer, I'd say its less likely a software issue (others would be experiencing it, if its a bug), and more likely a hardware problem, especially since you just had the screen replaced.

    Given Apple a call on this and explain the situation

    Probably will have to do that now. My macbook is out of warranty and I did the QP thing, will they be robbing me on this?

    If its related to the recent screen replacement, I would expect them to fix it for free.

    Better call Apple ASAP. For normal repairing, there should be a 3 months extra warranty. Not sure if it's applicable in your case. However, at least try to ask them to fix it (no matter it's hardware or software issues). The later you contact them, the less chance that they are willing to fix it for you.

    If the glitches not appear on the screenshot, that usually points to the VRAM (of course, screen failure also possible, however, it's very obvious that only the background has issue. So, almost can rule out the screen). But a very regular once every 15 wake up sound extremely strange for a hardware failure. There are basically 2 types of failure, intermittent or complete failure.

    For intermittent, should be quite random.

    For complete failure, should always happen.

    But your case didn't fall into either category. A regular intermittent bug :confused:

    Thanks for the info chief.
    Looks like a few more people have this issue. Read a few people complaining on reddit and there is one more on MR too.

    I went to the store for the GB checkup and since this was the fourth time I visited them for the same macbook in the last 3 months (logic board replacement, charger IO replacement, screen replacement) they offered to take my macbook in for store credit.

    Happy to take it specially when the new macbook is round the corner.
