I'm mainly using GNOME Shell, but I can confirm that it's working fine on Budgie and Enlightenment 0.19 as well. Although on Enlightenment, for some reason, GNOME apps don't scale right even though they're set to the correct HiDPI correction. No problem on Budgie with that. But non-GNOME GTK, Qt and EFL apps scale nice on Enlightenment though (and Aura, which is used in at least Chromium, Chrome and Yandex Browser).
Not sure how you'll experience it, but I did need to do a few tweaks to get everything scaled nicely.
Open up Tweak Tool and set the following:
-On the Fonts tab, set the fonts to an acceptable font size. I recommend 12-15. Then, set Scaling Factor to 0.70
-On the Windows tab, if not by default, set Window scaling to 1
Additonally, I found that the stock Shell theme doesn't scale nicely. Open up /usr/share/gnome-shell/theme/gnome-shell.css as root or sudo and look for the first fonts part. Set the font to something smaller. Now restart the Shell (ALT+F2 --> r --> Enter) and it scales nicely now. If you're using a custom theme and it doesn't scale right, edit the respective gnome-shell.css file of that theme.
