[Bug] Very minor background issue on startup

First off, this is a very minor bug i spotted when i launch the game in windowed mode (1920 x 1080, fantastic graphics, no other launch options).

Notice the background is upside down D:

Usually this fixes itself my moving the window or making the game full screen, however i thought i would bring it too light anyway.

P.S It annoys me more than it should, but why isn’t Play Game, Options and Exit capitalized!
