Eyestrain: No eyestrain feel confirmed, i can read for a whole day.
I changed my graphics card from AMD to intel, because I doubt the eyestrain feel is also concerned with graphics card.
It turns out AMD card produces eyestrain. Please use Intel card and avoid AMD in Linux operating system.
I also tried ubuntu 23.04, no eyestrain feel.
