that's a bug in Arc theme

(see nana-4/materia-theme#407 and https://gitlab.gnome.org/GNOME/gtk/issues/2237 for more detailed explanation of the issue and how to fix it)

however Arc theme got abandoned again recently: arc-design/arc-theme@53e6188

[actionless]

to workaround it you can downgrade both libsass and sassc to 3.6.0 or 3.6.1

[actionless]

also Flatpak package have bundled rather old libsass/sassc versions so there it also should work

[zygmund2000]

I confirm with libsass and sassc 3.6.1 it works.

In the upcoming Themix distribution releases support for Arc theme will be dropped: jnsh/arc-theme#47 since new upstream developers have no interest in it.

For Flatpak release mb it will stay til GTK 4
