For completness sake, pmap -XX $(pidof gnome-shell) shows 2G in Private_Dirty for me. I have since restarted Zoom so can't measure that.. Naively summing up the Size totals to around 9G. I assume that's the measurement you thought I was referencing. I agree interpreting memory usage numbers on Linux is hard. I also do think modern apps (including here gnome-shell and associated processes) eat up memory like it's unlimited and free.
