Gurm Ah ok so not the same thing as window manager compositing. My only safe computer is a 13yo 32bit toshiba running 32bit Xubuntu 16.04 that I am afraid to touch or update. I have an iPad 2 from 2012 stuck on iOS9 (which may be a blessing since higher versions seem to bother most people) but it crashes all the time and can't handle most webpages without freezing since there is no ad/script blocking possible on iOS9. My 2013 Nokia Windows Phone is fine as well but is deprecated and has no apps so isn't ideal.
I just cannot find newer HW that works and this stuff is too old to function much longer. I just want to run linux of any flavor or DE on decent laptop and desktop hardware. I don't care what brand or anything anymore...just as long as its pain free and capable. I don't use a phone long enough each day to be bothered by it and can deal with modern Android or iOS for simple phone tasks, so while that would be nice to solve too its not as important as a computer which is literally needed for me to stay alive at this point.
All the hopeful threads I find about linux like this one fizzled out https://ledstrain.org/d/26-on-arch-linux-xfce-eye-strain-problem-is-gone-unsure/13 and there is just no consistently safe combo I have seen posted. I have tried changing video drivers in GRUB as some suggested in the intel forums but that always just broke the DE.
*Also I remember the intel forum thread where the sent TUL or whoever the Thinkpad and I saw people say they didn't test for dithering...so we still really need to find a way to do that.
