Mail.app problem with external screen

Hello,

I've recently updated my MBP to High Sierra and found a problem with mail while using an external screen.

When Mail's window is in this external screen all the HTML content goes black (see attached image). This doesn't happen when the email is plain text.

Is anyone having the same problem and knows how to fix it?

I have a MBP Late 2011, 16GB RAM and 512GB SSD

In Mail I have Office 365 and Zoho.

Thanks for the help!

Nicolas.-
