3 years ago Aside from the issue shown above, there is also a more subtle problem with the way PDF anchoring currently falls back to quote-based anchoring in the event that the position selector no longer matches. See https://github.com/hypothesis/client/issues/3705.
When testing an upgrade to the latest version of PDF.js (v2.11.106) in the browser extension I encountered an issue where the highlights created for an annotation no longer match the originally selected text.
In the above screenshot, the annotation quote matches the text I originally selected, but the highlight does not.
The PDF I'm using for testing here is https://cogcomp.seas.upenn.edu/papers/RRDA11.pdf.
I also observed an issue where there was quite noticeable latency between clicking the "Annotate" button for the first time in a session and the annotation being created. The latency seems to be reduced when creating subsequent annotations. In a long book this could be confusing for the user as they may think that the "Annotate" button did not work. Likely related to this issue, I notice that the bucket bar is very laggy in updating compared to the production client.
