Comment 88 for bug 1672297

After some minutes I logged in (Ubuntu 18.04, gnome-shell) something used a lot of memory (approx. 1GB). I checked gnome-system-monitor, but there was not any process which used more memory as usual (neither user nor system). Nothing was opened or launched. Only one thing helped: logout and login again.
I have no idea what was that, and I can not repeat it again.
(gnome shell is extremely laggy :-( )
