Those icons often get out of control if you have a lot of apps. Even without the notch. I have been using Bartender for years for this reason. It lets you hide most app icons that only appear when you mouseover the menubar. It is a great tool. There are alternatives, like Dozer, if you don’t like to pay for software like Bartender.
I am really wondering if/when this is getting fixed, really strange that it is still happening.
