I have the same problem on ubuntu 21.04 wayland. Logging on under ubuntu xorg fixes it.
Windows sometimes don't close properly, and trying to exit can trigger a logoff. Manually logging off and back on fixes it for a while, until another window sticks. Thunderbird version 1:78.11.0+build1-0ubuntu0.21.04.2 Wayland is almost unusable because of this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1932328 Title: Thunderbird under Wayland does not correctly close (or manage) windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1932328/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
