Follow-up Comment #1, bug #509 (project tex4ht): Hi,
I don't have TL 2021 yet, but I think that TeX4ht should now load pgfsys-dvisvgm4ht.def by default, unless you specify \def\pgfsysdriver earlier. There were several versions of pgfsys-dvisvgm4ht.def in TeX Live, so it is possible that a wrong version is loaded on your system. What does the following command say? kpsewhich pgfsys-dvisvgm4ht.def You can try to download the most recent version from Github and to place it to the directory with your file. It should ensure that the correct version is used. Anyway, I've tried to compile your MWE and it seems to compile correctly with the recent driver. _______________________________________________________ Reply to this item at: <http://puszcza.gnu.org.ua/bugs/?509> _______________________________________________ Message sent via/by Puszcza http://puszcza.gnu.org.ua/
