It would be hard to prove that's a bug at all, or just the natural resident set size that the gnome-shell process settles at until the next garbage collection. And you can't predict or know when that will happen.
Generally speaking for gnome-shell I would say anything under 500MB might not be a leak. It might just be "normal" JavaScript garbage accumulation. Or it might be an asymptotic leak. Either way, not yet a priority. While we'd all like gnome-shell to always use less memory, whether this is a bug yet particularly in 20.04 where the memory usage is lower, is unclear. If you are able to repeat some steps many times and get 20.04 past 500MB and then 1000MB then I would consider it a leak worth investigating. ** Changed in: gnome-shell (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850201 Title: Memory usage grows when locking/unlocking the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1850201/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
