Yes, but it doesn't happen on my own mac so I'm having touble fixing it :/
Is there any way you could navigate to ~/Library/Logs/Fishlicka/Juice World/ on your computer and email me Player.log? (fishlicka@gmail.com)
No problem if you can't, it'd just help me fix the problem faster. In the meantime, you should be able to fix it by wiggling the pixellation slider in settings.
