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
GTK2/3 Normal apps are the legacy theme, Flatpaks in GTK3 need their own thing, and Flatpaks in GTK4 need an override. Then for GTK4 system apps you need to override the system theme. adw-override can do it i think but ive never done it before so do some research first if u try it.
