thanks for your advice, but i've already tried all that and there's no
obvious candidate.  my conclusion is that it's the rendering to x
surfaces that somehow is leaking memory, maybe when it refreshes, or
colors or some other graphical resource (but not specially images,
memory raises without displaying them).  there is no extension that i
don't use in one place and not the other, with the exception of
doc-view, but i know it's not the cause because memory grows up in X
even when i don't use it.  likewise, i know gnus is not the cause, nor
notmuch, because i see the effect with either.

judging from your experience, it must be an external package that causes
the leak, in graphical mode only, but i haven't been able to pinpoint
one so far.  perhaps i'll try with vertico/corfu next.

all that said, i'd be a bit surprised if the leak came from a pure elisp
package...

thanks,
jao
