LuaLaTeX+TikZ+fadings seem break SyncTeX

Postby pessoa » Tue Apr 23, 2024 1:52 pm

Hi.

If I use LuaLaTeX
lualatex -synctex=1 "main.tex"

to compile following document
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{fadings}
\begin{document}
text
\end{document}


and then try to use go to the source of "text" from the resulting PDF, SyncTeX will bring me to `<texlive>\2024\texmf-dist\tex\generic\pgf\libraries\pgflibraryfadings.code.tex`.

If I compile the TeX file with XeLaTeX or pdfLaTeX, SyncTeX works fine.

I'm using the latest TeX Live. The detailed versions are
# lualatex --version
This is LuaHBTeX, Version 1.18.0 (TeX Live 2024)
Development id: 7611

# synctex --version
This is SyncTeX command line utility, version 1.5
SyncTeX ERROR: Missing options
usage: synctex <subcommand> [options] [args]
Synchronize TeXnology command-line client, version 1.21

# using `/listfiles` command.

 ***********


I tried replacing "fadings" with TikZ libraries "calendar", "decorations", and "backgrounds", and all of them work fine with SyncTeX. However, "shadows" also causes SyncTeX to lead me to the `...\pgflibraryfadings.code.tex` file. I didn't test other TikZ libraries.

With more complex latex document than I was editing, the behavior of SyncTeX when using it with "LuaLaTeX" and "fadings" is different (and incorrect), but I can't find the minimal example.

I'm not sure where I should report this bug, please move the post if necessary.
