When I go in and change the engine in my wrapper I can even see this when the windows looking dialog comes up that says something about the wine configuration being updated. If that dialog has low res fonts then the app does too.
I've tried playing with the settings a bit, but nothing seems to work. If I use the mac driver I get a very small app window and the fonts seem to look ok when tiny, but it's obviously hard to use an app in miniature. Is there some other settings I should look at or is this a bug in the newer versions?
This is because the 10.8+ versions use a higher freetype version that caused a regression in Wine.
