This is the result with R2 2023 SP1:
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.
When RadPdfViewer is in text selection mode and the user is trying to select a word by double-clicking on it, the last letter of the word is not selected when the word is followed by some symbols like '.', ':', '(', '...'
Also, the CaretPosition is not correct.
The problem I'm trying to solve is that users do not know that the original document may not be what they are seeing in the viewer when there are layers.
A property that indicates
that a document has layers would allow the system to refuse to open the document.
Open the Demo app and load the PDF document with such annotation. The following error occurs:

Currently, RadPdfViewer offers the DataError event which is purposed to handle errors during the import process. However, if there are problematic pages that are rendered in the viewer at a later moment after the document is already imported, the viewer doesn't offer a suitable way for handling such problematic moments even though the PdfProcessing library throws one of its exceptions.
The exact client's case is loading a PDF document which contains images requiring JPX Decoder which is currently not supported. Even though the PdfProcessing library throws internally the following error, the RadPdfViewer control doesn't throw the DataError event with the respective error:
Telerik.Windows.Documents.Fixed.Exceptions.NotSupportedFilterException: 'JPXDecode is not supported.'
For example, if you choose to print second page like this:
It prints only the first page of the document, instead of the second page.
PdfViewer throws a "Position is out of range" exception when scroll.
There are cases in which some of the images in a pdf file appear with inverted colors. Resolution: The issue is duplicated with feedback item FIX. RadPDFViewer shows wrong colors Here is the link to item: http://feedback.telerik.com/Project/154/Feedback/Details/111786-fix-radpdfviewer-shows-wrong-colors
ADD. RadPdfViewer - add support for data fields
PdfViewer - does not arrange correctly the layout of some pages.
Description: Single Page View Displays one page at a time, with no portion on other pages visible.
To reproduce: When load the document, the text from file is not visible
FIX. RadPdfView - dragging RadPdfViewer to a form does not include the TelerikCommon assembly
There is no workaround for this issue.
To reproduce: When document that contain a specific formatting is imported there is some missing text.
