Compatibility Report
System Information
I confirm:
Symptoms
Game is starting, I can't see an image (game window is opened but all I can see are black and white squares, see attached file). However, I can hear the music playing and the game seems to react on buttons pressed (navigate through menu, starting the cutscene and the game, from what I can hear judging by changing of background music).
Reproduction
No other actions required.
