Not well. But at least I had windows at work to counteract it and I could turn the lights off. I also was a contractor for 15 years which meant working from my home mostly.

Strangely tho there is something about PWM flicker, especially the kind that is deep cycle (basically 100% on then 100% off) that are super bad for me. I can look at an old CRT fine because it’s not completely on and off as it does it’s scanlines. But PWM is like flicking a light switch rapidly and it gives me the worst headaches.

Yes, exactly that, modulation depth. The screen goes completely dark, and our brains don't like it because: 1. It's stressful that something disappears abruptly. 2. It's stressful that it later appears a bit shifted in space.
