I also see the same problem, in fact even more problems, and in fact with both gnome-terminal and xfce4-terminal. All these happened since I upgraded to Herd 3, and still persists till now.
General slowness with gnome-terminal is one thing. Sometimes typing a character to the shell takes a second to appear. Selecting with mouse is also very slow, especially when it involves scrolling. Scrolling by Shift-Up/Down is also very slow. Sometimes, I see "broken" characters (yes, part of the character is missing) inside the terminal, but when I select the text, the characters become alright. But they appear broken again when I deselect. I am using IBM T40 with P4M 1.4G and 768MB RAM. -- gnome-terminal mouse performance slow on feisty https://launchpad.net/bugs/78343 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
