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.
