I have this small dots appearing on my screen back and forth almost everyday.
I have been struggling with this issue over a while. Had my laptop given to the Apple Support Genius Bar. They changed my entire screen and still nothing. Have you got any ideas what could it be from?
Questa è una buona domanda?

You do have a very odd condition! This series uses a newer display system which places part of the displays logic (T-CON) within the uppercase as you can see here
But this doesn’t get into the drawing of the objects! As you can see the issue is not a global wash of a color or pattern (bars or noise). You have artifacts within a given object (a line in this case) The object is a drawn property based on Quick Draw the color within the line at different points is oscillating the background is not altering its color (either horizontally or vertically from the artifact in any direction)
This is a failure within the main logic boards graphics engine which composes the image and then tells the T-CON what is needed (not a display unit issue).
This will require a new logic board. I’m not sure I understand the persons logic not to come to this conclusion just looking at the info you supplied here.

Hi, Magdalena! Actually, any update? I have a similar problem with my 2020 MacBock Air. The screen and the logic board were replaced and the problem persists. Thanks!

@juandavidsierra - I doubt Magdalena will respond as its been well over a year.
The Intel based retina series of MacBook Airs have had this issue its a noise issue within the logic board. The newer rev board solved the issue.

@danj Thanks, Dan!

@juandavidsierra Hey there! Everything actually disappeared after I updated my laptop with the latest operating system. After that I haven't had any problems.
