tfouto Have you check your surface on microscope?
Yes, the results were similar to other laptops - alternating subpixel flicker pattern, but my slowmo mode won't catch the PWM for sure, since it's just a fraction of the frequency (120Hz vs. 21000Hz).
AGI Are you guys talking of the lights which turn on when someone in front of you breaks or turns left / right, or do you mean displays in your own car? What about traffic lights?
Some new cars have red / orange lights that are really intense - LEDs are usually brighter, but there are specific cars that standout - as if you compared phone screen at quarter-half brightness to its full capability. My wife who isn't affected by our issue also noticed it and it wasn't the case 2-3 years ago, so it's probably a new trend to make cars visible from a mile or so 😉
