I am trying to change my GTK theme via gnome tweaks buy that is no actual option to change the Theme via the appearance tab. I believe it is now listed under “legacy” and while the command line lists that my GTK theme is indeed changed to Material Black (the one I downloaded) the system windows still look like the default system settings. What is going on here
Have you installed the gnome-themes gnome extensions ? Once installed you can change the theme. Notice that shell theme and app themes are not the same thing. Also, notice that you need to take a gtk theme that supports gtk3 and gtk4 if you are using recent gnome
Allegedly I am using the right one. It works to change the Gnome shell but not the GTK themes
There is one for Flathub apps that needs to be installed on Flathub, one for old GTK apps, and one for newer GTK apps I think
