Description trmdi 2021-06-19 04:25:47 UTC 
When I use Material decoration on X, Firefox (without Kwin titlebar) uses it but it does not work on wayland, it uses the Breeze style.
Comment 1 trmdi 2021-06-19 15:46:05 UTC 
I've just found that somehow window_decorations.css is not used. When I append that file into ~/.config/gtk-3.0/gtk.css it works again.

Maybe relates to https://invent.kde.org/plasma/kde-gtk-config/-/merge_requests/17
Comment 3 trmdi 2021-06-19 18:08:19 UTC 
Or the gdk wayland backend does not read the module list from settings.ini? https://github.com/swaywm/sway/wiki/GTK-3-settings-on-Wayland

I can confirm this. In wayland gtk modules are not loaded.

If I set the GTK_MODULES environment variable, they will be loaded. But I don't know how to fix this bug in a right way...
