--- Comment #2 from sworddragon2@aol.com 2012-12-04 16:45:26 CST --- I'm wondering why this was working in Wine 1.5.17 and before. Maybe there was a bug which is now fixed in Wine 1.5.18 or their is a new bug.
I will attach a screenshot which compares my desktop with sharp fonts and regedit from Wine with smooth fonts. I will also attach all my font files. Maybe I have overseen something there but font smoothing should be disabled (I have experimented and set much more things to false without any difference).
