Not exactly flicker, but I have one monitor that makes an audible whining noise when certain spreadsheets are open and the window is sized above a certain % of the screen space.

It's maddening, but IT won't swap it out for me.

I say certain spreadsheet, but really it's something about the formatting and contents of a single page in that sheet. Open in Excel, noise. Snipping tool snip of the screen, also noise. That page printed to PDF and opened, however, does not make noise.

Life must have been rough when fluorescent lighting was the norm.

The standard thing was to turn off the fluorescent lighting back when everybody (tech support, sysops, programmers) was almost entirely looking at a screen.

I got very used to calling "lights" before turning them on or there would be moans and groans.

I had to quit one of my first jobs over it, the combination of cheap fluorescent lighting and no natural light caused me to have constant headaches.

You’re luckier than me, I get headaches from natural light.

If I’m outside on a sunny day without sunglasses I am pretty much done for the day. I have no clue why I am this way or if this is a common issue for folks out there. I should look into this more, and if anything can be done about it to reduce the nausea and headaches I get from being in the sunlight.

One of the things I’m looking forward to seeing is if wearing contact lens is better than wearing glasses.

I was pretty far down the road with a neurologist due to frequent migraines back in the day. Unrelated, I quit my job during that time. Suddenly, when using an LCD in a mostly naturally lit environment, instead of a CRT under fluorescent lights, my migraines completely vanished and haven’t come back once in a decade. Tada!

I thought I was imagining things in my head.

Another fix is to use DC dimming.
