Hello. I’m using Debian testing with KDE Plasma 5.27. I’m experiencing a problem where GTK Flatpaks are not following the chosen GTK theme despite giving them permissions to access .themes and .icons folders found in the home directory. I tried the running the following commands in the terminal:

flatpak override --filesystem=xdg-config/gtk-4.0:ro flatpak override --filesystem=xdg-config/gtk-3.0:ro

I even tried to specify a certain GTK theme to be chosen, that resulted in the flatpak changing to an ugly white-adwaita theme. I should note that this is happening exclusively with GTK Flatpaks, QT Flatpaks and GTK deb packages don’t seem to have this problem. What am I missing here? Any help would be appreciated.

    In this video explains everything you should know about flatpak theming.
    As others said, you probably haven’t installed the chosen theme yet.

    Old ass adwaita/libadwaita bug; happens on every distro… I’m really starting to think it is more related to libadwaita itself than to flatpak 😭

        Apparently there has been a problem with gtk4 apps and theming in flatpak, only supporting adwaita light and dark - only found vague reference to it though, nothing concrete.

        Try

        flatpak-metadata sockets

        To see if you can find the GTK_THEME environment variable.

        You’ve given it permission to access the themes folder, now you need go point it at the themes

        sudo flatpak override --env=GTK_THEME=my-theme 
sudo flatpak override --env=ICON_THEME=my-icon-theme

        Where my-theme is the theme name, e.g. Adwaita-dark

        Apparently the flatseal gui has some functionality to set the theme too! Will check it out tomorrow to see what’s up.

      here’s the same as text

      sudo apt install xdg-desktop-portal-gtk

      systemctl --user edit xdg-desktop-portal.service

      1. paste these two lines
      [Service]

Environment="XDG_CURRENT_DESKTOP=sway"

      systemctl --user restart xdg-desktop-portal.service
