Hi Telerik Support
We use your Telerik PDF-Viewer since your last Version "UI for WPF R1 2021" which supports Type 3 fonts.
Now the version runs productive by our customers. But after a day, they found some special PDFs that doesn't work quite right with your PDF-Viewer.
In the appendix you will find the PDf-Files as samples for the bugs that i'm describing.
Because of data privacy, the PDF-Files are cutted and cropped.
Also a demo project is appended (It could also be reproduced with the demo Progress Telerik WPF UI for th PDF-Viewer).
First Problem: Blank Page
Hint: It seems that only a few PDF-Files from a specific program seems to be a problem.
- Open Demo "WpfAppPdfViewer.exe"
- Open the file sample_1_blank_page.pdf(see appendix)
- You will see only a blank page
- Open the same PDF-File in another PDF-Reader like Adobe Reader and you will see a scan with an illegible stamp of an address
Second Problem: Displaying data delayed
- Open Demo "Progress Telerik UI for WPF"
- Open the file sample_2_delayed_display.pdf (see appendix)
- You will see only a blank page
- Wait approx. 5-10 sec. and you will see the content of the PDF-File.
I would be glad for a quick possible solution for our customer.
Best regards
Serge Schoop

Use the attached project to reproduce.
Workaround:
var combo = toolbar.ChildrenOfType<PercentComboBox>().FirstOrDefault();var binding = new System.Windows.Data.Binding();
binding.Path = new System.Windows.PropertyPath("ScaleFactor");
binding.Mode = System.Windows.Data.BindingMode.TwoWay;
binding.Source = pdfViewer;
binding.UpdateSourceTrigger = System.Windows.Data.UpdateSourceTrigger.PropertyChanged;
BindingOperations.SetBinding(combo, PercentComboBox.ValueProperty, binding);
var binding1 = new System.Windows.Data.Binding();
binding1.Source = pdfViewer;
BindingOperations.SetBinding(combo, PercentComboBox.RadPdfViewerProperty, binding);

In specific occasions, when starting multiple background threads to import documents, an InvalidOperationException might be thrown saying "Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct." This issue is pretty hard to reproduce.
