[Mojave] Games launch, and their audio works but I can't see them.

When I go to mission control they are transparent windows. GTA San Andreas, Terraria and Starbound all don't work. First GTA launched fine, but then I changed the settings, exited the game and ever since I can't launch it properly. I can see the window title, but there is no game. I keep seeing the steam library that i launch it from, I can hear the entire intro movie, but no video.
