If you want a confirmation about something then you should define the differences. A quick look shows some different colors. However you're using alpha for those colors and the form's background color is different in the two screenshots (which can explain the end result difference). > The > common source code is attached as well. > > Let me know if these are bugs and if a bug report should be filed.

With some more drawing experiments, I may have uncovered more bugs. I
need a confirmation. I attached two screenshots of renderings from both
frameworks (mono and ms.net), and they are noticeably different. The
common source code is attached as well.
Let me know if these are bugs and if a bug report should be filed.

[Mono-winforms-list] 1 pixel offset problem
Hi, I noticed that System.Drawing primitives will sometimes render things with a one pixel offset. I noticed that this affects MWF too, and I understand this is a libgdi problem, probably related to the fact that cairo takes pixel coordinates in a different way than Windows' GDI+. The attached screenshot shows the problem in the Cancel button right border of a MessageBox. I'm willing to try to fix this, but I wanted to ask first if this is a known issue or limitation of the current gdiplus implementation.
