--- Comment #96 from Anton Vorobyov phoenix@mail.ru 2012-08-09 18:10:07 CDT --- Also you actually have this bug, just in less noticeable form: look at luna's aura on your screenshot, then compare with:
1) http://bugs.winehq.org/attachment.cgi?id=41257 (luna's aura under wine with proposed fix) 2) http://bugs.winehq.org/attachment.cgi?id=41066 (luna with high video settings and 1.5.9+72 wine) 3) http://bugs.winehq.org/attachment.cgi?id=41099 (luna with reverted commit)
1st form is correct one, 2nd shows the most severe impact of this bug (when wine reports capability to support certain effects w/o properly processing them, as far as i understand), 3rd shows another form of this bug (when your system supports post-pixelshader blending, but wine reports that it is not able to do so)
You have 3rd one. Obviously it looks better than 2), but still not properly.
