That has to do with a change in GNOME or GTK, that now does compute
things differently for Wayland. GTK 4 applications are immune to it, and
I think there are ways to make GTK 3 behave as well, as the latest Gimp 3
scales correctly for example.

So it's not a Guix issue but a GTK/GNOME thing that will be resolved by
each application in time.

Closing.
