An empty page
Okular does not like empty pages (like page 4 from the attached document). Those pages can be extracted with
djvused j.djvu -e 'select 4; save-page p04.djvu'
Not critical but sometimes it ruins the comfort of reading.
i don't understand the problem. Can you be more clear? (In reply to Albert Astals Cid from comment #2) > i don't understand the problem. > > Can you be more clear? If you open the initial test file page 4 will be filled with garbage from the previous pages. My test page (extracted from the initial file) is half white/half black. For some reason, QImage::fill in kdjvu.cpp:499 cannot fill the whole page with Qt::white. Created attachment 127472 [details]

I don't get any garbage it's all correctly white here. Oh, actually i get garbage if i increase the zoom enough. Interesting. (In reply to Albert Astals Cid from comment #6) > https://invent.kde.org/kde/okular/-/merge_requests/155 Tested on my djvu collection. No regressions found. All empty pages are shown white. Thanks.
