Comment 2 Kjartan Maraas 2008-09-17 17:49:57 UTC 
I'm guessing this is just a general problem with huge messages, but I can't remember having been affected by it this much in a good while. I'm seeing this a lot while reading svn-commits-list from august.
Comment 3 Milan Crha 2008-09-18 14:18:26 UTC 
I'm afraid to say it's the way how GtkHTML works. Every 10 ms it updates the view when parsing email, if I change this to 250 ms, then it's quicker, but awfully flickers. When I do this on every single write to the stream it flickers even more. It recalculates the text's slaves to fit in line too, but no t only that is slow.

I bet on WebKit, which I was told will be included as mail renderer in 2.26. (maybe more than just mail renderer, will see).
Comment 4 Milan Crha 2008-09-18 16:43:48 UTC 
Err, I found a dupe for this, quite similar as this one, thus moving it there.
