Hi there,
First of all sorry for my English (I am French).
I have similar symptoms to many of you, but I'm not sure if it's the PWM.
It all started with the iphone 6 in 2015. Previously I used macbook, consoles, smartphone, Ipad without any problem.
I bought iphone 6, played 2048 a lot, and all of a sudden couldn't use hardware with a screen. Symptoms are exactly the same as motion sickness: stomach ache, difficulty walking, dizziness.
Looking at an iphone or ipad makes me sick after 10 seconds. I feel like all recent screens (since 2015) are making me sick. Especially at apple.
I use dark themes, disabled animations and motion blur, but it's still not comfortable enough.
Today I still manage to use my 2012 MBA which is starting to get really tired.
I bought an MBA M2 a week ago. It's nicer than anything I've tried recently, but it's not perfect. Maybe I'll get used to...
I bought a PS5. Not easy either. It's mostly on 3D games, fast camera movements...
Another thing, I feel uncomfortable in some malls when the lighting is too strong.
Beyond the PWM, I wonder if something else bothers me. For example scrolling or photo scrolling is what makes me the most sick. Do you think it's from the PWM or something else?
Thanks :-)
