Acrobat Reader - just for comparison
The checkboxes in this case look much nicer - but that is a different story.
Also the Acrobat reader does not display any text, but just big checkboxes - it would be nice if the same could be achieved for okular. Can we have the actual file? Created attachment 135027 [details]
PDF file showing the problem
Sorry for the missing attachment - i have attached the file now.
Probably an issue in poppler, but needs investigation. I have reproduced this issue with Okular 20.12.2 and Poppler 21.03.0. I opened the "PDF file showing the problem" in Okular, clicked "Show forms" ticked a box, hide the forms and saved the file. The box no longer shows up after hiding the forms. I further confirmed that Evince, which is also based on poppler fails to show the checked box. In fact, clicking any other box in Evince will also fail to show. Finally, I confirmed that opening the modified PDF in either Master PDF Editor [1] or Firefox 86 does show the ticked box. Thus I agree with Albert that this is most likely a poppler bug. @Andreas, would you like to report the bug at https://gitlab.freedesktop.org/poppler/poppler/-/issues/ ? [1] https://code-industry.net/masterpdfeditor/ a proprietary PDF software with Linux support I opened a related bug at https://bugs.kde.org/show_bug.cgi?id=433979 which however, unlike the current one, is not reproducible with Evince. I filed a bug on a similar problem, with radio buttons: https://bugs.kde.org/show_bug.cgi?id=442849 It appears forms are badly broken. I have even seen, in every version up to 21.08.1, text entry boxes that won't display the user entered text, if it's after a radio button or check mark box. Just for future reference, it seems that Andreas did file a bug report for poppler: https://gitlab.freedesktop.org/poppler/poppler/-/issues/1055 After 2 years with this annoying bug, all I can do is continue using browsers to work with PDFs with forms. looks like i am not the only one annoyed by the bug -> shall collect some money to sponsor the work/fix ? => https://discuss.kde.org/c/development/sponsored-work/31 |
