Slide Thumbnail creation creates wrong results (C# .NET)

Crating a thumbnail of the attached PPTX document yields improper rendering.

        const float scale = 300 / 96f;
        using (var ppt = new Presentation(@"ConversionIssue.pptx"))
            ppt.Slides[0].GetThumbnail(scale, scale).Save(@"ConversionIssue.pptx.jpg");
        } (340.2 KB)
