Sometimes problems with the visibility of threads in thunderbird

[Joachim Backes]

Hi all,

I'M running thunderbird-24.6.0-1.fc20.x86_64. Sometimes (rather often,
but not always) having problems with threads in thunderbird: After
opening a thread, all opened sublines are unvisible, until I move the
mouse pointer over them (without click): then they will appear.

This happens both with ati and nvidia video cards.

Anybody has this effect too?

Kind regards

Joachim Backes
