How is that? Wine claims to use the system settings for for rendering, and as can be seen in the screenshot, it clearly differs from the system settings. Hence this is not properly implemented, and clearly relevant to this bug ("Use the *system desktop setting* for subpixel font smoothing.").
Wine just renders the fonts differently. That's all.
