Screen flickering on 16" macbook pro
My screen has started flickering rather as if the triggering of the video is intermittent.
It started off suddenly and sometimes appears to depend on how far I open the screen, I used to be able to find a "sweet spot" where it was normal but less and less and now it hasn't been normal for a few days.
There are 6 vertical stripes on the screen with spurious flickering up and down on them.
MacBook Pro 16″, macOS 12.1
