MAC Game Doesn't Fit Fullscreen Anymore

Played a game after today's updates and for some reason in Fullscreen mode more than 75% of the game screen is just off my laptop screen.

Relogging and restarting the laptop did not fix it, switching to windowed mode did. This has never happened to me in 2 years of playing so I assume it has something to do with today's updates.

I'm on a Mac, idk if anyone else has seen this issue.
