- The interface moves from 87ab8179 to libcosmic master of 2026-09-24, which brings its newer winit and accesskit forks and upstream's menu, context-menu and maximized-window fixes.
- The accesskit_winit build failure newer libcosmic has on Windows does not reach this build: macOS and Windows disable libcosmic's default features, a11y with them, so no accesskit crate compiles there. Enabling a11y on Windows would need a patched accesskit, as the pin's comment notes.
- The lock keeps gpu-allocator on windows 0.62.2, the version wgpu-hal 28.0.1 passes it; the update had re-resolved it to an older windows, breaking the Windows build with mismatched Direct3D types, and a later cargo update can do so again.
- 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.
