Mail content display delayed

[jpw]

WebApp: 3.5.2+dfsg1-1
Kopano Core: 8.7.0

Hello,
does anyone know the reason for the following effect: After logging in and clicking the Inbox folder, the subject lines, etc. are displayed. However, the content of the first marked mail does not appear immediately. Only after clicking on another mail does its content appear. And if you click on the first one again, including its content.

Thank you very much.
Jens
