Green squares glitch

[mikimikimiki]

Hello, I would like to ask if any of you have had the same issue.

Since the day I bought my MBA 2020 (i3) in September 2020 I am having an issue with the screen. It shows QR Code-looking green squares in two, maybe three spots on the screen. It happens randomly, sometimes twice a day, sometimes once in a month and I have no idea how to induce this issue. I work mostly with Excel and Word. These squares show up for a split second and I am never ready with my camera to take a picture of it, but I found an exact case on Apple forums, from where I'm posting a picture. During the glitch Mac freezes for a brief moment and comes back to normal. It is not software related, was there on Catalina and Big Sur and with fresh installs.

As you say, it is not software and there is not much we can do here. Better contact Apple and get it fixed before warranty expires.

Send it to Apple. Book a Genius Bar appointment. Maybe they can do something.

You can't induce the issue because it's most likely an intermittent hardware failure. Those tend to worsen with time (or just go boom at all once and you have no computer). As others have said, consolation with Apple is the only viable solution.

What was the cause and fix in the thread with the image?

I had this with a 2011 iMac a few years ago with something very similar, it was a dying graphics card (the best i could determine, it was not worth the money it would have costed to fix). The odd thing is that it was temperature related, I put it in an unheated garage and it would happen every time, if I left the computer running (to heat up the internals) it would only happen every few boot attempts.

Obviously, this symptom could have multiple causes, but it indicated a hardware problem for sure. Hopefully you have AppleCare, or can still purchase it as I think a hardware replacement is in your near future.

2011 iMac odd graphic corruption

Hello, I have a 2011 iMac, running High Sierra, and have gotten a weird static like graphics corruption that happens somewhat intermittently. I was able to do a screen recording and uploaded it to youtube so you know exactly what I am talking about: Do you think this is something related to...

Yeah, I did send it to Apple and I am waiting for the outcome. I will let you guys know.

The thing is it doesn't appear on screenshots or screen recordings, that's why I don't have any footage of it.
It still is under warranty so hopefully they will positively diagnose the issue and make it disappear

You have a picture in post 1 and could also do a video from (phone) camera, but hardware errors will rarely appear on screenshots and screen capture.

I have just received an email from Apple. They have found the issue and they are replacing logic board and Touch ID.
