diop Linux/MacOS has always been worse than Windows for me, however now I am at the point where I can use no modern OS/PC in comfort.
Are you using a laptop? Which panel is it, TN or IPS? It matters, because this Zbook of mine got the worst possible TN-panel, which alone is causing me plenty of discomfort. However, I can distinguish between those things and crappy panel is something I can still live with, but the eye-strain on Linux is a total no-go and I've had it on all kinds of displays. It's always there. I can't work like that, but I seriously want to leave Windows. I'm tired of their experiments on people.
diop Do you use Windows 10 and experience discomfort?
I'm still on 8.1. However, when I first got this laptop it had W10 preinstalled and no, I didn't detect any visual problems other than those related to the panel.
diop Also, do you have any known eye conditions? (e.g. amblyopia/strabismus)
I do have a little problem, which I believe I got from Linux years ago when I was still unaware of it. I think it's antimetropia/anisometropia. One is plus, the other one is minus. Maybe it was just a coincidence, but I repeat, my sight got worse when I was still using Linux (Debian), and because of that I had to move back to Windows because I couldn't take it no more. However, since it doesn't bother me when I'm Windows, I presume, it hardly matters? Not to say I don't have to go see ophthalmologist, but it's not going to change how things are on *nix systems, is it?
diop This issue which many devs seem to think is just a pesky little ‘bug’ is affecting people’s health. I can’t overstate the seriousness of this issue, however I’m sure you’re well aware of the discomfort we’re all going through.
Obviously, the low-profile nature of the issue, a number of collateral factors and exceedingly small number of people affected by it leads to disbelief and negligence on part of devs, therefore it is our duty to bring this to urgency.
diop I suddenly developed the same symptoms on my good machine as a bad one.
It happened with me once too back on Windows 7 and GeForce GT240. Something in Nvidia settings went off and the screen weirdly enough started looking just like Linux with the same level of fuzziness which soon enough made my eyes tense. I DON'T KNOW what happened, but when I rebooted the machine things were back to normal. It never happened again since.
I think we should also contact Xorg devs, I have a hunch it may have something to do with it. Also, I will try using Wayland instead and see if the issue is present there. I honestly doubt Nvidia and ATI are to blame here. If there are any IRC users around feel free to join #xorg, #xorg-devel and #wayland.
