Flatpak uses broken Adwaita theme in KDE Plasma
Last modified: 2024-06-19 02:45:16 UTC
Open Firefox, Thunderbird or any GTK4 app in Plasma and they will appear with a GNOME theme, with a huge Adwaita cursor. This seems to be caused by the most recent Flatpak and/or xdg-desktop updates. Apparently doesn't happen on X11, only on the Wayland session.
Resolved a long time ago. https://github.com/flatpak/xdg-desktop-portal/issues/1112
