Sound bar GUI glitch on MacBook

macOS Big Sur 11.0.1 (20B29)

I vigorously swooshed the sound bar in an attempt to turn the music down.

And for some reason, the bar sound is now stuck on the screen as shown in the picture below (Also, if I take a screenshot, the bar doesn't appear in it).

The bar is draggable and functional like the normal bar.

enter image description here

I tried to do both but to no avail.

killall Dock
killall Finder

How do I get rid of it without having to restart the computer?


After figuring out what service was responsible for the bar I tried

killall ControlCenter

And it did the trick
