Highlighting some PDFs makes text vanish
Maybe this is a bug. In some PDFs when I highlight text and save, a page or two of the text vanishes and I am left only with blocks of yellow. Googling led me to what seems like a workaround: if I right-click the PDF in Zotero and choose Manage Attachments to send it to another folder, I can see all text (including that which is highlighted). I think I might have raised this some time ago but I can find no evidence of it, so perhaps I imagined having done so. I can provide screenshots demonstrating the issue if that would help anyone. Thx.
