Everyone knows that macOS always has the current application's menu in the top immovable bar. Not that I'm strongly against it, but it seems that globally something crazy is happening with windows and their menus in macOS. Two examples.
As a password manager, I use Bitwarden, and after initial setup, this menu now doesn't show up at all. Bug obviously on Bitwarden's side. I can't even open settings!
Telegram. Here the menu is fine, but macOS doesn't see Telegram's windows! On Mac, a running application without a window is somehow normal, which is exactly why when you close all windows the icon in the dock sometimes still remains or such incidents happen. By default Cmd+Tab switches between applications, including those without open windows, yeah. And the absence of a Telegram window during such switching isn't very noticeable, but if you install something like AltTab or Contexts, which switch between windows (like in Windows), then the picture is as follows - the window sort of exists, but when switching it sort of doesn't. They fixed the bug just the other day, and even then, only in beta.
Both are obviously application problems. But I have thoughts that maybe the system is to blame for such bugs being possible in it at all.
