Created attachment 133886 [details] shows as blank white page In several pdf documents, entire pages are displayed as blank white surface. This is not the case when I open the same PDFs using other tools, e.g. Firefox. pdfinfo does not report any problems. The attached page demonstrates one such problem. I do not attach other documents because they are copyrighted. However, I am happy to provide these files directly to developers.
This is a poppler bug. Can you please open a bug report at https://gitlab.freedesktop.org/poppler/poppler Thank you! Confirmed with current git master. Both atril and Okular render a blank page, so supposedly it is not a backend-specific bug. OTOH, xpdf 4.02 does render text, so trying to figure out what it does differently seems like a promising approach to fixing this.
Evince and qpdfview do not show the page either. pdfimages from poppler 20.12 reports: Syntax Error (20660): 312 extraneous bytes after segment Syntax Error (20660): First JBIG2 segment associated with a page must be a page information segment Syntax Error (49226): Invalid segment reference in JBIG2 text region Syntax Error (49226): 11517 extraneous bytes after segment pdf2ps -> ps2pdf gives the result that can be shown in Okular. So this must be the poppler problem. I'd recommend reporting this bug against poppler: https://gitlab.freedesktop.org/poppler/poppler/-/issues/new?issue
