Thank you for your bug report. Could you give exact steps, when you say 'mess around with showing title or not', does it mean that if you open that dialog, click the box one, close thunderbird you get the issue? or you need more clicks?
does it do every time? could you do $ journalctl -f trigger the issue and see what is printed on the journal log? ** Changed in: thunderbird (Ubuntu) Importance: Undecided => Low ** Changed in: thunderbird (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902969 Title: Thunder freezes UI when changing from title bars to CSD To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1902969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
