@p @NEETzsche @mint I don't use the KDE desktop but there's few apps from them that I use like Krita and Marble (Desktop OSM client).
That said krita ended up in my OpenSuSE chroot that's usually for chromium/steam/…

gtk works fine without dbus, at least gtk3, gtk4 is broken by default without it due to lack of dconf (where the d is probably related to dbus) but it's somewhat fixable.
