A display problem: the dot that represents differential disappeared

windtracker · July 12, 2022

There is a dot above letter that represents differential in control engineering.
The PDF reader in Zotero didn't display the dot correctly, but Acrobat could display it normally. Both software opened the same PDF document. Is it a bug? or the specific document caused?

Does it help if you disable hardware acceleration?

I have tried disable hardware acceleration just now, however it doesn't work.

Could you send us the PDF file to support@zotero.org also including a link to this thread?

Also please describe how to locate the specific part of the PDF file that is causing the problems.

windtracker · July 12, 2022

Yes,of course. I will send you the PDF file with problem description later.

The issue will be fixed later this year, when we upgrade our underlying PDF reader engine (PDF.js).
