I'm not sure what just happened but this webpage literally damaged my monitor. There is now some flickering over the whole screen (it's not my mind, I filmed and checked my mind with another screen)

I've been having problems with my Mac M1 laptop display (4 years old), and this kicked them back in.

But to be clear: display was already having issues and i have a service appointment to get it replaced

yeah that happened here too. Was it an LG?

Yes! It's an LG Ultra HD running at 2560x1440 @ 60Hz

Same monitor here. Damn strange. I'd experiment more if I didn't need to work with it. Keeping the monitor off for awhile seemed to help , but a quick off/on didn't.

What type of monitor is it?

Dell Monitor – P2722H. A common LED LCD

It's not even a year old.

Yup, I turned it off, disconnected it from my Mac and left it for a minute, then rebooted. All seems fine now.

Warning: This just fucked my 2k$ 4k LG display. I ran the website 15 minutes ago and quickly closed it after 15 seconds. My screen is still flickering in the portion of the screen where it used to be the webpage. I rebooted. Still happening

FML please put a big disclaimer.

Just a warning - running this for a few seconds has left my secondary display with an ongoing flicker which seems to be improving after 10 minutes and a reboot. [edit to add] 10 minutes later - the flicker has gone (or I can't perceive it)

Same with Dell P3223QE.

Same here, on a Dell P2421DC (2560 x 1440 @60 Hz). It is especially noticeable on darker colors (grey or black backgrounds).

Same here!

I went to github and see that we are not alone

I have the same, but a thought crossed my mind that it somehow stimulates your vision so that you start seeing the flickering which is always there
