A bit off topic, but there’s that “Plasma Workspace” app title bug on your matray’s notification screenshot! I’m glad I’m not alone experiencing that little annoyance. It affects a few other but not all GTK-based apps too, so the culprit seems to be xdg-desktop-portal-kde. I’ve made a post about it a long time ago; since I’ve seen you make contributions to the KDE codebase, please do check it out.
