Can not read the content of the mail

Ever since High Sierra upgrade, certain email messages are all blackened. Sometimes the reply is blackened. I am not able to see (read) the content of the message. This behavior is only on Mac mini mid-2011 and not on my MacBook Air.

Any help would be appreciated it.
