This sounds like the first fix for the issue which probably explains why it mostly went away in 20.10:
https://github.com/micheleg/dash-to- dock/pull/1266/commits/a8c0e1ece7b69e893943ab44a561e8ab2979551f The fix is missing in 20.04 still. But performance of deleting files is still poor even in 22.04 so I'll see what I can do about that before suggesting backports. ** Bug watch added: github.com/micheleg/dash-to-dock/issues #1265 https://github.com/micheleg/dash-to-dock/issues/1265 ** Also affects: ubuntu-dock via https://github.com/micheleg/dash-to-dock/issues/1265 Importance: Unknown Status: Unknown ** Changed in: gnome-shell-extension-ubuntu-dock (Ubuntu) Status: Triaged => Fix Released ** Tags added: fixed-in-69 fixed-upstream ** Project changed: ubuntu-dock => dash-to-dock ** Also affects: gnome-shell-extension-dashtodock (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-shell-extension-dashtodock (Ubuntu) Status: New => Fix Released ** Changed in: gnome-shell-extension-dashtodock (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell-extension-ubuntu-dock in Ubuntu. https://bugs.launchpad.net/bugs/1876641 Title: gnome-shell leaks hundreds of megabytes when the dock option 'show- trash' is enabled.
