If you are talking about messages of several hundreds kilobytes size or  
more: it is a "problem" of GtkTextView widget. It is doing then some  
internal revalidation of the buffer (computation of text size after  
wrapping, for example). If you wait few seconds (minutes?), ordinary  
scrolling behaviour should be restored. There might be some  
programatically settable options to speed up the process but I must say I  
have not looked for them yet.

I have just tried to reproduce it on my setup but I see only moving  
scrollbars - the view is updated properly (this is with gtk2-2.2.1-4) -  
but I have impression I have seen the problem you describe. -Pawel
