It was reported almost a year ago!
The error also occurs with short names, for example with the photon plugin.
Oh must've missed it, sorry. Your report is incomplete anyway so I'd say keep this one.
It is caused by long names. It can occur for any name as long as there is a long name somewhere visible. I found a reliable way to reproduce and would appreciate if it could be looked into. Temporally workaround is to make the window as small as possible, so it displays content on a single column.
