Vertical Artifacts on display, external monitor not affected.
When I open the macbook (A2141) the screen is ok at certain acute angles but if opened too far it corrupts to a rash of vertical lines of multi-coloured artifacts. If I gradually close the lid, there is a point at which it clears up but opening it again produces the same error. I've heard of a similar issue but involving the backlight on the 16" macbook pro's so this sounds like the same problem. Is there a fix for this, covered by a similar recall of affected machines? This has the potential to be a major cost otherwise.
MacBook Pro 16″, macOS 13.2
