STEPS TO REPRODUCE Try to generate PDF tooltips using \pdftooltip from pdfcomment latex package https://ctan.org/pkg/pdfcomment Currently, you can see its effect looking into the package documentation for example (page 14, hovering over the equation for example) http://mirrors.ctan.org/macros/latex/contrib/pdfcomment/doc/pdfcomment.pdf OBSERVED RESULT It shows nothing EXPECTED RESULT It should show a tooltip On linux it works with Evince as it was implemented there: https://gitlab.gnome.org/GNOME/evince/-/issues/882 It is still waiting to be implemented in poppler: https://gitlab.freedesktop.org/poppler/poppler/-/issues/34 On Windows, it is properly supported with Adobe Reader and Microsoft Edge for example Thanks SOFTWARE/OS VERSIONS Linux/KDE Plasma: Gentoo (available in About System) KDE Plasma Version: 20.04.3 KDE Frameworks Version: 20.04.3 Qt Version: 5.14.2
