I just figured, this also happens, when mails are opened regularly.

This looks like it could be an upstream issue. Could you please file a bug at https://bugzilla.mozilla.org/enter_bug.cgi#h=dupes%7CThunderbird and share the link to it here? Thanks!

Created attachment 9255156

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

- Update XUbuntu from 21.04 to 21.10 (now Thunderbird version 91.3.1)
- Open mail (preview or with doubleclick)

Actual results:

Mail opened, but button area in the top of the mail is cropped (see attachment screenshot.png). Buttons "Reply", "Forward", "Archive", ... are only seen 50%, as well as "From" line.

Expected results:

Button area should not be cropped.

This bug was also reported on launchpad: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1954587

Hm...
For some unrelated reasons I had to reboot my system a couple of times today and now the problem seems gone.
This is a little weird, because I rebooted several times before, but the problem kept appearing.

For now I'll close the bug.

Ack, thanks for following up. Feel free to re-open if the problem surfaces again.
