For what it may be worth: i have had 1:x lines of chat appearing in uni chat now and again also. i tried various superstitious conjectures out to be rid of them. What now seems to be working is: when starting the pc, having logged into Linux i first start the ryzom game using the installer software to start the game (ie to call the launcher).... only when that has finished do i enter the password. then first if at all do i start a browser (firefox) to also use Rocket Chat.
Result: 1.1 in uni chat (last couple times that is so far)
On the other hand, when i was having multiple text lines appearing in uni chat, i had started perhaps simultaneously the game installer, LibreOffice (in order to take notes now and again) and also the Firefox browser, with several tabs including the Rocket Chat. That did not always, but all too often seem to provoke the multiple lines in uni chat phenomena. And also ofc the PW it seemed to me would after a time begin, not sure if always before the multiple lines output began or not.
hope that somehow helps
