So even with the bug fix and everything, this happens when I attempt to open the game. Changing the resolution does nothing. The game is...technically playable, though only about 75% of the screen.
had a similar issue but instead of it being full screen it was a very small window. To correct this if you press (function) F1 it will open up a small window that will have a block for full screen. Yours is probably checked so if you just uncheck it that should fix your issue. If that isn't it.... I got nothin.
Also i found that when it goes to full screen it opens partially like the picture you posted.
To make it fit your screen after you start the game you then click another program, after that click the urban demons game icon again and it'll fit itself to your screen.
So itll be something like this.
double click the game app
urban demons opens up all but doesnt fit right
then click your internet explorer or anything else so the game isnt the priority app open
then click the urban demons game icon on your bottom toolbar and then itll fit your screen correctly.
Hope this helps
