From http://www.smart-games.com/supportfaq.html:
On Mac or Linux the graphics is bad, there are boxes around the stones.
This is a bug in Wine and other Windows emulators. Update 12.020 has new graphics code that avoids this bug. Upgrade to the latest release to fix this problem.
So maybe this Wine bug has not been fixed after all...
Indeed my version is 12.022. archive.org is currently down but when it comes back I'll try to get older versions and test again.
