[MBP 14" M3] Is the display faulty?

[farmaceut]

A weird thing happened today. While using my MacBook Pro M3, the screen suddenly displayed vertical, rainbow-colored bars on the left side before and immediately returned to normal. I wonder whether this was due to the app issue or something's about to happen with the display? Got AppleCare+ until November.
Thanks.

More likely the GPU on the M3 than the display, IMO. If it happens again, try to capture a picture of it, and take it to the Apple Store.

Did you upgrade to Seqouia yet? If so, there's a known issue with weird flickering on the desktop — artifacts appear for a moment, disappear immediately, and you might observe this up to once every few minutes. (Well, "known" as in I have experienced it myself — 16" M2 Max system — and seen a few other users complain about it here.) If you are on Seqouia, I'd wait until the next update before getting worried about this.

Yes. This is upgraded to Sequoia. It happens only and just once.

I have a 2021 MacBook Pro, but so far it only has Sonoma on it.

A suggestion:
First, back up all your data.

Then... try the "erase all content" option to completely reset the MBP back to "moment zero".
By that, it should boot just as you took it out of the box and opened the lid for the first time, with "no personal data" on it, waiting to be set up.

Then, restore from your backup using setup assistant (part of the initial boot process).

Seems to me this should KEEP Sequoia, while removing all personal data (and preference files, etc.).

No promises.
Just a suggestion...
