White lines? Need help

[BNR32]

Just installed the demo, and i keep seeing these white lines. And in some parts of the game there are white boxes covering areas. Any suggestions? Thanks.

That's very weird :|

Maybe it's a problem with the demo, because it seems the colours and the textures for the menu options are also missing :|

And have you tried putting on Vsync in the graphic options to remove that diagonal line?
