Hi Haithem,

Thank you for the feedback.

I checked in our backlog for reported issues related to rendering performance and these are the results I found:

• PdfViewer: Improve the rendering performance of documents with many geometries.
• PdfViewer: Slow import of documents containing large image with SMask

However, I am afraid the provided information is not sufficient to determine the exact reason for this behavior, so I would like to ask you to send us the document causing this behavior in order to deeper investigate the case. I must assure you we treat all client files in a strictly confidential manner and for testing purposes only.

Looking forward to hearing from you.

Regards,
Martin
