Aspose.Diagram upgarde destroys images - While visio to png conversion

Hi Aspose,
Currently we are using Aspose.Diagram 18.10 and we wanted to upgrade to 19.11. If we replace this dll, some images do not render correctly.

Problem 1 :
Input Visio: Extra Image shown_Old.zip (88.3 KB)

Output Image:
Version 18.10 : Extra Image shown_Old.PNG (17.9 KB)

Version 19.11 : Extra Image shown_New.PNG (21.3 KB)

Problem 2 :
Input Visio: Extra Space shown_Old.zip (76.1 KB)

Output Image:
Version 18.10 : Extra Space shown_Old.PNG (3.3 KB)

Version 19.11 : Extra Space shown and Question mark icon_New.PNG (7.0 KB)

Problem 3 :
Input Visio: Icon Position changing_Old.zip (41.6 KB)

Output Image:
Version 18.10 : Icon Position changing_Old.PNG (1.4 KB)

Version 19.11 : Icon Position changing_New.PNG (1.4 KB)

Problem 4 :
Input Visio: Question Mark Icon position change_Old.zip (44.1 KB)

Output Image:
Version 18.10 : Question Mark Icon position change_Old.PNG (4.8 KB)

Version 19.11 : Question Mark Icon position change_New.PNG (4.8 KB)
Sample Code:

string strInputPath = @"C:\vj\2019\Visio Issues\Old";
			string strOutputPath = @"C:\vj\2019\Visio Issues\New\";

			string[] files = Directory.GetFiles(strInputPath, "*.vsdx");

			foreach(string strFile in files)
			{
				Diagram vdxDiagram = new Diagram(strFile);
				ImageSaveOptions opt = new ImageSaveOptions(SaveFileFormat.PNG)
				{
					SmoothingMode = SmoothingMode.HighQuality,
					CompositingQuality = CompositingQuality.HighQuality,
					InterpolationMode = InterpolationMode.HighQualityBicubic,
					PixelOffsetMode = PixelOffsetMode.HighQuality
				};
				vdxDiagram.Save(strOutputPath + Path.GetFileNameWithoutExtension(strFile) + ".PNG", opt);
			}

We are waiting for your reply and support.

Thanks.
