It seems this issue is related to SCIM which is started by Chromium (when it's not started yet?). Removing all the SCIM related packages solved the issue.
I suspect this bug is still present for people that need to use SCIM. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1579533 Title: Chromium process doesn't close when closing the last window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1579533/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
