Soo.. I use a Macbook Pro and recently upgraded to OSX Mavericks, it worked perfectly fine, but this problem has occurred before. The graphics seem to be wayyy more pixelated than they should be, and just off. Usually when I completely exit out of FH and re-open it, it fixes, but now it just stays pixelated, it almost looks like the entire game is made out of individual dots. If anyone has any suggestions on how to fix it, etc, it'd be very appreciated, as I don't want to have to redownload FH and have to replace all my files. Thank you.
