Comment 13 for bug 1672297

I see the same leak you do when interacting with the panel. In fact, just pressing the Meta key twice to bring up and hide the overview leaks 1 MiB of RAM each time. Even switching workspaces leaks memory. These are all things that jank once gnome-session's footprint has grown to unreasonable sizes, so presumably that jank is a symptom of bloated datastructures taking more cycles to negotiate.

Attached is another profile, from a session that didn't end with Wayland pooping its pants.
