The numbers I reported by garbage-collect do not account for the memory
usage. FWIW I've posted that info again at
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=43395

In 2019 i suspected the culprit was the fonts system.  It doesn't seem
to be toolkit related. I don't use emacs as an imageviewer (but I have
to check that). Since the interest in CONFIG_PSI there are a number of
tools on github that monitor memory - it should be possible to come up
with some tool that alerts emacs of memory surges while keeping some
history.
