My googling also suggests that it might be low frequency flickering and PWM/dithering. Turning on night light/redshift does not help. Turning on dark mode doesn't help either.
For the PWM thing, I tried the solution at https://superuser.com/a/707852/1261816 but that only made my screen go dark and removed ability to change brightness while not helping with eyestrain. I think that solution works for some specific older GPUs only. I also tried solution at https://ledstrain.org/d/785-eyestrain-when- switching-from-windows-to-linux/24 for PWM on my screen but I think that is outdated too as xrandr didn't seem to recognise the option. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1920106 Title: Eye strain on using ubuntu but not windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1920106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
