Hello, I posted the same to dev-lua...@ntg.nl <https://app.hey.com/contacts/122193413> but it still was not approved by a moderator, so I am reposting it here.
When compiling a trivial doc \documentclass{article} \begin{document} a\kern3pt b \end{document} we get the following synctex kern nodes in the .synctex file: x1,4:10110238,8865054 k0,0:8799518,8865054:196608 x1,6:10671226,8865054 g1,5:31409438,8865054 kTAG,LINE:H,V:WIDTH compare to pdflatex: x1,4:10670937,8865054 k1,5:31409438,8865054:20738501 g1,5:31409438,8865054 pdflatex seems accurate, but luatex often produces huge numbers as tags and other attributes on longer files. Log preamble: This is LuaHBTeX, Version 1.16.0 (TeX Live 2023) (format=lualatex 2023.8.28) 22 NOV 2023 03:42 system commands enabled. **main.tex (./main.tex LaTeX2e <2023-06-01> patch level 1 L3 programming layer <2023-06-30> ... Other nodes seem to be fine. Will be happy to do some debugging if needed, or file an issue somewhere. Thanks, Dmitry
