free, distributed and user-friendly IRC client with Twitter, and XMPP/Jabber support for Linux, Windows and macOS based on GNOME / GTK+

Yes, I am working on it already. The problematic GUI queue based on Gtk.ThreadNotify is being replaced by GLib.IdleHandler. The concept is much different, when Gtk has nothing to do (no draws, no updates etc) then the IdleHandler will be called. In that IdleHandler method it will work on the queue (GUI changes that are pending, like showing new IRC messages to the channel pages) and does the actual work. This means when gtk is "done" or "ready" for making new changes to the GUI, then Gnosmirc will process his changes. In practice this should give a much more interactive GUI programm (when its under load). The GUI hangs should not happen anymore this way, since if gtk has alot to do (making new pages, updates userslists etc) then no further GUI changes are done (from the queue) till gtk has finished first the current pending work. Also what I like about this approach is, I wrap the IRC callbacks into the gtk main thread, so I don't have to create containers for each GUI change (that was a real PITA)! The rewrite is not completed yet, the svn repo is inconsistent now, so be careful if you svn update ;-) Allright thats it for now...
