I noticed in one of my machines still running Gnome 45 that QT apps were invisible due to: https://gitlab.gnome.org/GNOME/mutter/-/issues/3435 https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3475 It seems a bit hard to backport, hopefully we will be able to update to 46 soon, but I open the bug here for the users that could hit it now that nvidia-drivers got their wayland/gdm support fixed
