I too get the output as posted. (mtx-context     | current version: 2024.09.25 11:53)

If you change the following MWE line

    \connection [bt] {compiler}

to

    \connection [br] {compiler}

then the glitch goes away, so I suggest that means it is a bug in the flow chart module.

Changing to draw from the bottom shape upwards also has the glitch on a straight line - so something to do with the straight line drawing code, perhaps?

As a work-around, if you just want the section heading underlined (as opposed to a more complicated MP graphic that you omitted for simplicity) then your MWE becomes:

\usemodule[chart]
\starttext
\subsection[title={\inframed[frame=off,bottomframe=on]{Introduction}}]

\startFLOWchart[toolchain]
\startFLOWcell
  \location{1,1}
  \connection [bt] {compiler}
\stopFLOWcell

\startFLOWcell
  \name {compiler}
  \location{1,2}
  \shape{product}
\stopFLOWcell
\stopFLOWchart

\FLOWchart[toolchain]
\stoptext


If you don’t want the section number then use \subsubject instead of \subsection.
