I just received a MacBook Air M2 few days ago and I noticed that the display flickers even more than old MacBook Pro, and especially with gray colors (worse temporal dithering?) My config is: 8 core GPU / 16GB / 512 SSD
Here's a slow-mo comparison video with my MacBook Pro 13 2018 (both at max brightness, filmed at 720p 240fps) : https://www.youtube.com/watch?v=5IuuoJR-4BU
