Thanks for the report of your typical usage.  To make this even more
complete, could you please post the full information collected by
"M-x report-emacs-bug" about your system and the Emacs configuration?

To make some progress in investigating this and similar reports, it
could help if you start a fresh session, in which you check the memory
footprint frequently, say, each hour.  When you see a significant
increase in the memory usage, try to remember what you did since the
last checkpoint, and report this information here.

TIA
