i dont know if we can call that a bug, but once the notchbar is activated, when i put anything in full screen, like iina ,vlc, or youtube through a browser, the notch bar stay visible, and sometimes not. but i will prefer not 
I'm working to improve this, for now you can always right-click the NotchBar and select the "make black" option to get rid of it.
perfect thanks 
Is this still being worked on? It makes it impossible for me to use the Notch Bar when I am using Microsoft Remote Desktop which requires full screen mode for multiple monitors and the notch bar obscures necessary Windows controls.
