For a Flatpak application to follow the system theme in use, the corresponding Flatpak theme needs to be installed. For example, if I use the "Yaru" theme in "Dark mode" with the "Prussian Green" accent color, the "org.gtk.Gtk3theme.Yaru-prussiangreen-dark" needs to be installed. If it is, both system applications and Flatpak applications look consistent. However, only a few themes are available in the Flathub repos. If you search for Yaru themes on Flathub (flatpak search Yaru), you will notice there are alot of variations, but only the packages not presenting a "Version" number correspond to the new 22.04 Yaru theme. As such, only the following Yaru (22.04) themes have a correspondent Flatpak theme:
Yaru Yaru-dark Yaru-sage Yaru-bark Yaru-bark-dark Yaru-prussiangreen Yaru-prussiangreen-dark Yaru-olive Yaru-olive-dark Yaru-magenta Yaru-magenta-dark For a consistent look between Flatpak and non-Flatpak applications in Ubuntu 22.04, the missing accent color themes need to be available in Flathub. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970282 Title: Flatpak apps are not properly themed if a accent color other than the default is choosed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/yaru-theme/+bug/1970282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
