Have the same issue with KDE Neon 5.17.3 with latest packages. The software versions are:

KDE Plasma Version: 5.17.3
KDE Frameworks Version: 5.64.0
Qt Version: 5.13.2
Kernel Version: 5.0.0.17-generic

The preview doesn't work in Kmail (also when Kmail is opened within Kontact), opening the mail in new window shows the proper content. Changing Composer setting didn't help. The graphics driver in use is i915.
