Then, you're not using gdiplus directly but using some intermediate library?
Does this patch have any effect? https://www.winehq.org/pipermail/wine-patches/2013-February/122317.html
Indeed: System.Web.DataVisualization.dll. However, the issues are only solved if I use the native gdiplus.
As for the patch, I would not know how to apply it! I developed the software for a specific scientific purpose and my programming knowledge is limited (working with Visual Basic).
