While experimenting with screen resolutions to solve the fullscreen issue, with some of them I was getting parallel lines displayed across the very first loading screen after launch and onwards, including actual gameplay sections. 1400x1050 didn't have this issue for me, but your mileage may vary.

If you're getting black screen after trying to initiate fullscreen, try experimenting with your desktop resolution. The game doesn't seem to like 16:9. What worked for me was 1400x1050. In my case, the game window is shifted downwards a bit (I can still see my desktop's top bar, and when there's more than three lines of text in the game's text box, only about 75-80% of the fourth line is visible).

Slight cursor desync that others have mentioned.
