This is a bit annoying when an app has its own menu near the top of the screen. The only app I use in full screen is a media player. Every time I try to interact with the in-app hamburger menu, the whole wind shifts and the system window bay animates out.
I really don’t like the full screen behaviour in macOS.
Apple would say they don’t like hamburger menus. If the app is designed contrary to the guidelines (which say avoid hamburger menus) and tries to fight the system, unsurprisingly it’s not going to work well with the system.
IntelliJ also has a menu bar just below the top of the full screen. I wish Apple made the collapsing top menus require much more insistence before appearing.
