my chat window for a Jabber contact got into a state where when I send a message the text scrolls up to the beginning and stays there. An incoming response doesn't change this - I would have to scroll down manually. Only restarting Jitsi would solve the problem until it comes back.
I cannot exactly say which event would trigger this kind of behaviour - maybe I myself scrolled up for reference or the other side disconnected and came back, or my side changed the outside IP due to DSL disconnect.
Has anyone else seen this?
