Comment 9 Leslie Satenstein 2018-03-27 03:26:52 UTC
Here is a way to demonstrate a memory leak.

Begin your gome session.
Invoke "system" (a gnome utility) that shows memory use by application name.
focus on gnome-shell
On a fresh logon, the shell will show around 200megs consumed
invoke aisleriot  a few times and exit
Each time aisleriot is invoked, it consumes around 5 megs
On exit, the 5 megs do not appear returned to the shell.

More simpletest. 
invoke aisleriot and then firefox and then aisleriot
you will find that the gnome-shell memory use is monotonic increasing, even after quitting firefox and aisleriot

Other gnome programs cause a similar effect.

Programs that do not use gnome-shell (Dropbox), on exit, return all memory that was assigned.


Footnote.
Is the monotonic memory increase shown by gnome-shell due to the shell or to Aisleriot / firefox, both not releasing memory back to the system?
