I'm trying to track down something that makes system performance degrade
in less than an hour. Whenever I switch desktops, move my cursor to a
place where a tooltip is displayed, open a pull-down menu, the display
freezes for 5-15 seconds before, for example, the menu or tooltip is
released.

If I kill -1 my gnome-shell, performance is restored...for a while.

I decided to take some measurements.
% ps guax | grep gnome-shell
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
skelem   15805  6.3  0.6 4037064 401804 tty2   Rl+  10:10   1:07 
/usr/bin/gnome-shell

The VSZ and RSS grow slowly, if at all, if I don't switch desktops, bring up 
menus, etc. Here are snapshots at 15 second intervals:
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
skelem   15805  8.5  1.3 4755216 862708 tty2   Sl+  10:10  10:41 
/usr/bin/gnome-shell
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
skelem   15805  8.5  1.3 4755216 862912 tty2   Sl+  10:10  10:42 
/usr/bin/gnome-shell
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
skelem   15805  8.5  1.3 4755216 862912 tty2   Sl+  10:10  10:43 
/usr/bin/gnome-shell
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
skelem   15805  8.5  1.3 4755216 863128 tty2   Sl+  10:10  10:44 
/usr/bin/gnome-shell
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
skelem   15805  8.5  1.3 4755216 863344 tty2   Sl+  10:10  10:45 
/usr/bin/gnome-shell

After 2 hours, the ps reports go from
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
skelem   15805  6.3  0.6 4037064 401804 tty2   Rl+  10:10   1:07 
/usr/bin/gnome-shell

to
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
skelem   15805  8.7  1.2 4725708 821640 tty2   Rl+  10:10  11:27 
/usr/bin/gnome-shell

VSZ increases by 688.6K, or 17%.
RSS increases by 419.8K, or 104%

I'm running GNOME Shell 3.26.2 on Ubuntu 17.10 x86-64.
