The interactive plot works fine.
The PDF file flickers when opened, as if multiple layers are rendered over each other before settling.
The issue is noticeable during zooming the pdf file

            using FileStream stream = File.OpenWrite("Plot.pdf");
           
            //2) Create PDF Document with Fixed DPI
            using SKDocument pdfDocument = SKDocument.CreatePdf(stream, new SKDocumentPdfMetadata
            {
                Title = "ScottPlot PDF",
                Author = "Your Name",
                RasterDpi = 300 // Ensures high print resolution
            });


            float pageWidth = 8.5f * 72; // 8.5 inches @ 72 DPI = 612 points
            float pageHeight = 11f * 72;   // 11 inches @ 72 DPI = 792 points

            //  4) Begin a Page in the PDF Document
            using (var pdfCanvas = pdfDocument.BeginPage(pageWidth, pageHeight))
            {
                plt.Render(pdfCanvas, (int)pageWidth, (int)pageHeight);
                pdfDocument.EndPage();
            }

            pdfDocument.Close();
