- The window never had a title, so taskbars and window lists showed it as untitled on every Linux desktop; it is now titled "Midi Harbor". The header draws its own title, which is why it went unnoticed.
- On X11 the window's class comes from argv[0], because the pinned libcosmic replaces its X11 window attributes with its Wayland ones. The desktop entry's StartupWMClass is now midi-harbor, the class a package install gets, so X11 taskbars match the window to its entry and icon; Wayland still pairs by the application ID.
