The possible workaround is to use the old Pdf processing model, by setting the UsePdfProcessingModel property to false.
this.radPdfViewer1.UsePdfProcessingModel = false;
// This switches the thumbnails to the old model too. Otherwise they are blank.
this.radPdfViewer1.ContainerElement.ThumbnailList.UsePdfProcessingModel = false;
Hello, Al,
Indeed, the feedback item is completed. Please have in mind that the fix will be released in R1 2022 SP1 which is scheduled for the second half of February.
