  2. Unable to select certain areas to add annotation.
    As you can see in the below images, we are unable to select most of the text on right end of the pdf page. Also you can see that the text selected on Annotation on the PDF is different from the text on the comment. For example here we tried selecting the text Metals Mining. Annotation on PDF page is applied to Metals (highlighted in yellow). In comment panel Mining is shown.

Expected behaviour

  1. PDF should be rendered properly.
  2. Should be able to select properly and annotations are added correctly.

Does your issue happen with every document, or just one?
several documents we have tried and can replicate the issue.

Hi @Sriraman,

Thank you for contacting support.

Can you tell me about these documents you are experiencing these issues on; are they converted word documents, scanned documents, linearized?.. etc.

They are not converted from Word application. They are not scanned documents. Not sure about linearized.

Hello sriraman,

Unfortunately PDF rendering and PDF text selection are handled by the PDFJS library. Please open a ticket to resolve this with Mozilla.

Actually I do not see these issues with PDF JS. There is no rendering issue when the page width si 50% or 70% or 100% or page width. I can also select the text without any problem.

Please refer the below snapshot.
