The current implementation of "Windowed (Fullscreen)" mode on macOS is broken, and does not function the way it's supposed to. It doesn't work, It is basically the same as Windowed mode. When correctly implemented, while running apps in "Windowed (Fullscreen)" mode on macOS, the app should be full-screen (no window border, taskbar or dock visible) and a three finger swipe (on touchpad) or a two finger swipe) on the Magic Mouse switches out of the fullscreen window (sort of like tabbing out of something on Windows). This works correctly in many other games, such as World of Warcraft and games from the new Apple Arcade, but it's broken in The Elder Scrolls Online.
The alternative to this would be to use "Fullscreen" mode but when playing The Elder Scrolls Online in "Fullscreen" mode, I am unable to swipe out of it in order to view other apps. I'm basically locked into the game unless I disable Fullscreen mode. Playing in a window is not ideal and having to disable "Fullscreen" mode in order to view Discord or Safari, for example, is cumbersome.
The game's resolution also seems locked to the current scaling settings in macOS Catalina, so I'm unable to change the resolution to take full advantage of the 4K display. Other games (such as World of Warcraft, for example) have this setting implemented correctly where "Windowed (Fullscreen)" mode functions like it's supposed to (It is actually fullscreen and I can swipe out of it to access other apps) and the game resolution can be changed to a higher setting than the current scaling of the macOS desktop (I can run the game in 4k and then swipe out to my scaled 2k desktop and other apps). This is broken in The Elder Scrolls Online.
Please review the latest guides from Apple in order to correctly implement "Windowed (Fullscreen)" mode on macOS:https://developer.apple.com/library/archive/documentation/General/Conceptual/MOSXAppProgrammingGuide/FullScreenApp/FullScreenApp.html
The game performs really well on macOS but this bug is a huge frustration.
Steps to reproduce:
- Play any other game on macOS or run any other app in "Windowed (Fullscreen)" mode; notice how it is actually full-screen (and if it is not, you can click the little green icon on the top left to make it so), you are then able to swipe out of it to the desktop and/or to other full screen apps.
- Play The Elder Scrolls Online on macOS in "Windowed (Fullscreen)" mode; notice how it is just Windowed mode; it's not Fullscreen. The green Fullscreen toggle button is also missing from the top left of the window when playing in "Windowed (Fullscreen)" mode.
EDIT: Fixed terminology, included dev guide link on how to fix the issue, and moved discussion from Bug Report forums to Mac Support forums.
