Hello,

I'm experiencing an issue where the fonts in my emails are appearing jumbled and unreadable in Thunderbird. This seems to affect both the subject lines and body text of emails, as you can see in the attached screenshot. Some details:

This is happening with multiple emails, not just one The issue persists across different senders and email types

I'm using Windows 11.

Has anyone else encountered this problem? Do you have any suggestions on how to fix it? Thank you in advance for your help!

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

Non-english letters like č and ć are displayed as ? in Correspondents in the Thunderbird mail list and in From in the individual mails. Not known to the font Thunderbird uses? Can I change that font?
