Sorry about the display stuff. It seems to be completely dependent on your system, so I'm having a really hard time tracking down the problem since it looks perfect on my PC. As for the music, do you mean it's skipping? Or not looping properly or something?
The music will skip at certain parts when I'm in the lab, but as for looping, it loops just fine. I have a pc that uses windows 8.1 so I don't know if it's just how the game works on my laptop or if it's really a problem. I run other VNs on my laptop and they work absolutely perfect.
