Comment 28 for bug 1672297

No matter what you do, gnome-shell eats up RAM slowly. In case you shutdown your machine after every use, you will not notice it, however, if you keep it running or tend to suspend/hibernate, it will reach a point when it will swap.

After one day of usage (just web browsing) gnome-shell increased ram usage from 100M to 350M. It does not free it up even if you close all windows. In my 4GB machine, it means that either I restart every day or I start facing swap issues the second day.
