The issue is reproducible only on Windows XP. On newer versions of windows, the images are rendered as expected.

WORKAROUND: You may try implementing custom filter that handles the CMYK scenario. How to implement custom DCTDecode filter is described in this documentation article:

When the font is not embedded in the document, PdfViewer tries to read it from the OS. However, the Calibri-Font is not properly parsed and a NullReferenceException is thrown internally for its encoding.

Steps to reproduce:

1. Load a PDF document with 0 pages

2. Enter some text in the search textbox and click the next/prev buttons

Expected: the search textbox should be either disabled or should ignore any search operation

Actual: an error occurs

Workaround:

    Private Sub pdf_Viewer_DocumentLoaded(sender As Object, e As EventArgs)
        If pdf_Viewer.Document.Pages.Count = 0 Then
            pdf_Toolbar.SearchTextBox.Enabled = False
            pdf_Toolbar.NextButton.Enabled = False
            pdf_Toolbar.PreviousButton.Enabled = False
        Else
            pdf_Toolbar.SearchTextBox.Enabled = True
            pdf_Toolbar.NextButton.Enabled = True
            pdf_Toolbar.PreviousButton.Enabled = True
        End If
    End Sub

Use the attached pdf document and launch the PdfPrintPreviewDialog. As it is demonstrated in the gif file, the preview dialog moves the pages slower than the pdf viewer itself.

Expected behavior: the performance for navigating the pages should be at least identical.

If the DataError is handled, you can detect what kind of internal errors occur. The document is loaded successfully at the end. If the thumbnails menu is hidden, the load time is much faster.

Load a document with bookmarks and select the bookmarks options. Then, move the splitter:

Expected: the selected option (bookmarks) is unchanged

Actual: the selected option (bookmarks) is not preserved and it is reset

Is there a way to load this RadFixedDocument into a RadPdfViewer without writing the document to a file first and then loading it in the viewer?

Workaround:

You can achieve the desired functionality by exporting the RadFixedDocument to a MemoryStream instead of a file in the file system and then load it in the PdfViewer: 

RadFixedDocument document = CreateRadFixedDocument();

PdfFormatProvider pdfFormatProvider = new PdfFormatProvider();
Stream ms = new MemoryStream();
pdfFormatProvider.Export(document, ms);

radPdfViewer1.LoadDocument(ms);

            try
            {

                while (true)
                {
                    using (RadPdfViewer pdfViewer = new RadPdfViewer())
                    {

                    }
                    Console.WriteLine($"iteration {i}, elapsed seconds: {stopwatch.Elapsed.TotalSeconds}");
                    i++;
