The icons and UI elements are super-big
The workable area of the window is limited to the 1/4th of the screen.
libreoffice became completely unusable.
Probably related with:
But that one seems to affect wayland support, are you using it?
No, I don't. I'm on X session.
After examining my process list, I found out that indeed gnome 3.22 makes the wayland session the default. The session names in gdm are gnome and gnome on X now.
I switched the session to X and libreoffice is back to normal.

In 3.20 I think it was running wayland for gdm, but gnome session was still running on X... maybe we should revert to X as I am unsure how mature was wayland support... but we still have time to decide I guess :/
Pushed gtk+-3.22.4, please check if it fixes this issue for you.
According to upstream NEWS, it should.
I confirm that upgrading to gtk+-3.22.4 fixes the issue with enourmous UI elements sizes on HiDPI display.
