Some filled-in form fields display blank in Adobe Reader
wget https://www.irs.gov/pub/irs-pdf/f1040s2.pdf launch evince open f1040s2.pdf Fill in example numbers in lines 4 and 10. Save As... test-1040s2.pdf
On the same Ubuntu-18.04 machine, in both xpdf and evince, all of test-1040s2.pdf displays as expected, specifically including the form entries.
Copied f1040s2.pdf to a (virtual) machine running MS-Windows-10, and opened in Adobe Reader DC 2021.001.20142 . Expected: display correctly, specifically the form entries in lines 4 and 10. Actual: no form entries show up in line 4 or 10, as seen in tax-pdf-adobe-reader-w10.png file from screenshot (lines 4 & 10 circled in red with the gimp).
Ubuntu-18.04.5-LTS, evince-3.28.4-0ubuntu1.2
