--- Comment #8 from Leonard Lausen <leon...@lausen.nl> --- 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/ ?
