0.10.11 OBS fullscreen game bug

When I want to use OBS with the game, there’s a problem with the fullscreen mode.
Since there’s no graphical option to put the game in fullscreen, I use ALT + Enter.
Like you can see here, it only shows a quarter of the game

But the menu is displayed like it should, so it’s a bit strange

So in order to stream, I’m forced to play in windowed mode.
