no. I am using multi-gnome-terminal. I strongly dislike gnome-terminal (
a nice thing is that it has no probs with locales/ can use utf-8
though). It also happens in xterm. Scrolling speed in xterm/mgt is
comparable... gt is much slower...

What I find interesting is that the system (not cpu!) load is maxxed to
100% all the time when scrolling in 2.6. but less than 50% in 2.4....

Sounds like the some kernel driver eating up the time... which I thought
could be due to the new radeonfb driver....

Other ideas ?
