KWin's Wayland debug console can be minimized. The minimize animation plays as normal, except that it doesn't minimize towards the task manager. Once the animation finishes, however, there's still something eating mouse events at its old geometry. The only way to bring the window back is try to guess where its corners were and then starting a resize, after which the window will magically re-appear and then you can close it. Invoking the DBus method again will spawn a second debug console rather than restoring/closing the previous one. (I didn't test whether it's actually the debug console getting the events or KWin just blocking them at this location but in any case, I can't interact with the windows within that area)
