System76 has added some improvements to the GNOME's HiDPI implementation. I'm not entirely sure what the improvements are but for example they've got a HiDPI daemon. Anyway, last I used fractional scaling (this is GNOME built-in), I ended up giving up because it just refused to work properly. I have a ultra wide 4k screen, plus my laptop screen. I really wanted to have my laptop screen at 4k when plugged in with 2x scaling, and the ultra wide 4k with 1x scaling, but it caused more trouble than it was worth. So I eventually gave up. Fractional scaling was an experimental feature when I used it, around 12 months ago, so it could have improved.
