Wait, how do you see the notch? It seems that only the menu bar can go there and fullscreen and windowed apps and video can't. Why circumstances do you see it?
Maybe it's because I use dark mode? I can only tell it's there if I move my mouse under it.
When menu items no longer show up because they're where the notch is. Happens every time I'm on just my laptop and not on an external monitor.
I have my display scaled a bit smaller than default, which is probably why I never see that. That's....so stupid.
Here's a "workaround" that might help [1]. It entirely excludes the notch area from use.
