I've tried using the fix in https://tex.stackexchange.com/a/492197/193767 in order to make TikX's remember picture feature usable, Code below, just in case: \unprotect% This fixes the present bug\unexpanded\def\pdflastxpos{\numexpr\clf_lastxpos\relax}\unexpanded\def\pdflastypos{\numexpr\clf_lastypos\relax}% This might be needed if you run PGF 3.1.3% see https://github.com/pgf-tikz/pgf/issues/675\def\XC@tgt@mod#1{#1}\def\XC@sdef#1#2{\edef#1{#2}}\protect\usemodule[tikz]\starttext\starttikzpicture[remember picture] \node (A) {Node 1};\stoptikzpicture Hi world\starttikzpicture[remember picture] \node (B) {Node 2};\stoptikzpicture\starttikzpicture[overlay,remember picture] \draw (B) --++(0,0.5) -| (A);\stoptikzpicture\stoptext However, the following appears: l.1 6 120806 \lastxpos ->\clf_lastxpos <write> \noexpand \pgfsyspdfmark {pgfid1}{\the \lastxpos }{\the \lastypos } <inserted text> }\endwrite <argument> \shipoutscratchbox \page_shipout_box #1->\clf_shipoutpage #1 \relax \setbox #1\emptybox \global ... ... l.20 \stoptext I use LuaTeX 1.10 7127 + ConTeXt MkIV 2019.03.21 21:39 (TeX Live version), in case this helps. Is another fix necessary? A Metapost alternative would be fine, too.
