    I've implemented a small sample using the RadPdfViewer control.

    Here's the key part of the MainWindow xaml:
    <telerik:RadPdfViewer x:Name="pdfViewer" Margin="144,41,0,0" />

    And here's the code that loads one of the three test documents in MainWindow.xaml.cs:
                this.pdfViewer.DocumentSource = new PdfDocumentSource( 
                    File.OpenRead( @"..\..\documents\LudwigVonMises.pdf" ), FormatProviderSettings.ReadAllAtOnce );

    When it displays, the document is missing the title image (which appears in other readers like Foxit and Acrobat).
    It also has odd text kerning issues, such as excess spaces or letters over-running each other.

    On another document, it renders the title image but it's distorted.

    I've attached a sample of the poorly-rendered text.

    Are there other settings I can exploit to correct these issues?

    There are no settings that will allow RadPdfViewer to render PDF documents better. You should note that there are some features (images, elements, colors, etc...) that RadPdfViewer does not support. They are listed here.
    It would be great if you could open a support ticket and send us the documents that you have problems with. In this way, we could investigate the cause of the issues.

    All the best,
