Gnome 44 support

[Koitharu]

This extension does not work on Gnome 44 beta (Wayland, haven't tried x11). There are no exceptions, the settings work fine, just no effect.
It would be nice if Gnome 44 was supported as well. Thank you

[Koitharu]

I'm not sure that it will be enough. In my case version validation is disabled, extension can be used as usual, but selected applications still have light appearance

Header bar still light, before upgrade to gnome 44 it was working

Hi @Koitharu, the extension uses xprop to set _GTK_THEME_VARIANT to dark. So it only works on x11 or with xwayland apps. You can check if your app is xwayland by running xprop in your terminal and then click on the window you want to enable dark variant.

I guess this application is running using xwayland

In x11 session I got the same effect (not working)

[BartleyTheShopkeeper]

I have experienced the same issue as well.

It seems GTK3 was dropped in Gnome 44 and now every app uses a GTK4 headerbar. So probably this trick will simply never work again :(

The support for _GTK_THEME_VARIANT has been removed from mutter 44 and probably won't be added again as you can see at https://gitlab.gnome.org/GNOME/mutter/-/issues/2792.

Is there any update regarding this problem, I am using on gnome 45 and it doesn't work. I hope there is good news for this extension

[jonian]

Ηι @mudza09, unfortunately there is no update. I made the extension compatible with gnome 45 in case the issue gets fixed. I will update this issue if there are any good news.
