Upstream bug report was closed and is here https://gitlab.gnome.org/GNOME/evolution/-/issues/1972 I was also affected by this bug. It seems to be an issue with libcanberra-gtk3-module, which I had no real need for, so I was able to uninstall and it appears to have solved the problem. ** Bug watch added: gitlab.gnome.org/GNOME/evolution/-/issues #1972 https://gitlab.gnome.org/GNOME/evolution/-/issues/1972 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evolution in Ubuntu. https://bugs.launchpad.net/bugs/1978260 Title: Evolution not closing emails after sending To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/1978260/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
