Are you using a custom theme? It might be incompatible and causing this, see e.g. Bug 427270. Please switch to Thunderbird default theme and retest. If the issue persists also check the Error Console and copy/paste the messages here.
The comment of Mr. Sitter was correct. I have been unsing the theme walnut 1.7.18. After changing to another theme Lightning is running correct. To be honest, I would never have thought it could be, because it belongs to lightning and is offered with it.
Please leave the resolution the way it is, since there is no patch on this bug that would "fix" this bug. The walnut theme is not offered with Lightning, it is separately available from https://addons.mozilla.org/thunderbird/addon/1495
