Intermittent stage lights effect on MacBook Pro 2019
I've been the happy owner of a 13" MacBook Pro TouchBar 2019 since July 2019. Everything was working great, until a few weeks ago, my screen started randomly showing the infamous "stage lights effect". (see picture here)
Note that the computer was never tampered with, never saw any liquid, I've been taking great care of it over the years.
However, the problem seems to be software to some extent because running
pmset displaysleepnow, then re-unlocking it gives me a bright screen for a few minutes... Then it goes back to stage lights.
I haven't been able to determine what makes the problem appear, but it usually never takes more than 10 minutes to appear once I start using the computer.
Is that a known issue? I know the Apple doesn't do repair programmes for MacBook Pro 2019 for the flexgate issue. And as far as I know, the programme for the keyboard, which may have helped, has been discontinued too.
Thank you in advance for any suggestions!
Is this a good question?
