Hi Dalyoung !
I am not entirely sure, but there is a strong chance that what you are
observing is related to internal changes in LMTX between your 2024 setup
and the current 2026 version. In particular, the way glyph outlines are
extracted and passed to MetaPost seems to have evolved. Your current
code relies on:
|draw outlinetext.b(...) |
This belongs to an older MetaPost-based mechanism for outlining text. In
recent LMTX versions, the preferred and actively maintained method
appears to be |lmt_outline|, which handles OpenType fonts (especially
CJK scripts like Hangul) more consistently.
Could you try this code instead? And tell the list what differences you
notice? I made a few changes, concerning the blue color, but mainly the
use of lmtx in the MPgraphic call and the line below (present in the
original script).

Dear Hans,
Sometimes I use the outline font style for chapter title.
Yesterday I got the strange output of it which was good at 2024.12.
Here are two figures, first one is the output of 2024 and the second one is the
output of yesterday.
Is there any changes of method of drawing outline fonts?
I attach a sample file and two figures.
Thank you.
Best regards,
Dalyoung
