Version: (using KDE KDE 3.4.3) Installed from: Ubuntu Packages OS: Linux Trying Kopete for my first time, i was using the Adium chat style for IM. When I tried IRC, it used the same chat style, and that dropped my PC performance a lot. If I switched to a simpler chat style, like IRC style, all worked fine. If I could use IRC style for IRC and Adium style for my IM protocols i wouldn't need another IRC client. My suggestion is that you should be able to select a chat window style for each protocol.
Possibly same as bug#122410
Dear user, unfortunately Kopete is no longer maintained. Please migrate to another solution, e.g. for Jabber a possibility is Kaidan, for Matrix a candidate is NeoChat.
