Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

No, i have yandex, gmail and my own dovecot server, and everywhere problem exists.

Is the issue reproducible with a particular attachment, message, signature, etc?

No

Hey folks! Well, the good news is I've finally gotten this to happen on my machine (or at least, something mostly similar.) The bad news is that even with the app attached to Visual Studio the output is still mostly garbage - hopefully will get to the bottom of this. Definitely seems arbitrary and probably caused by some characters / data sent by the IMAP server, but it's unclear why it'd be a windows-specific issue.
