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. ** Attachment added: "Valgrind Massif profile of leak during normal use" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1672297/+attachment/5002843/+files/massif.out.3205 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1672297 Title: gnome-shell uses lots of memory, and grows over time To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1672297/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
