Yeah, we’ll start unsetting GTK_THEME from libadwaita in future, there’s a lot of confusion around it:
- How to let GtkMenuButton be flat using GtkBuilder?
- GTK_THEME breaks adw_style_manager_set_color_scheme ADW_COLOR_SCHEME_PREFER_DARK (#677) · Issues · GNOME / libadwaita · GitLab
- numerous times in Matrix
- etc.
Some apps already unset it: for example: build-aux/org.gnome.World.PikaBackup.Devel.json · main · World / Pika Backup · GitLab
