Using it daily on my 1920x1200 laptop screen in Linux and works just fine.
My desktop monitor is 1920x1080. On my computer and display; Vim, Emacs and VSCode are all able to render their fonts crisply while Zed is a blurry mess.
I use it in dark mode and I am considerably less picky about font rendering than many people commenting on such threads.
Combined, while I can see a difference if I look closely, it doesn't bother me.
