How to cause the problem:
1. Click on someone to spectate
2. If the spectation just started loading(connection request start), and you press Alt+F4(call osu!fade+outro sound then exit) at the same time, while the spectated player is constantly pressing reply, thus the spectation cannot fully load, then the client acts weird and the "ExitCommand" gets interrupted and does not exit the game.
Now that the "osu!fade mode" have been called and executed and the "outro sound" ended and the "ExitCommand" got interrupted, the game will continue to run with the "osu!fade mode on" and it looks like this:

While you are in this mode, you cannot interact with the UI, but when you move your mouse the "BackgroundShake" effect still persists, so the mouse is still detected and you can still hear every sound (song, hitsounds, etc., except the UI sounds).
I had to terminate my client to exit osu!
