gnome-terminal exhibits an odd display problem on occasion when using an irc client with a dedicated window for messages. Every now and then, the current base of the terminal window shifts up to where the message window is if there are currently messages occuring. This bug is not present in xterm or rxvt. I believe its a zvt rather than a gnome-terminal issue. If I run it from a screen and detach and reattach, the resulting refresh restores the terminal window An example of how it looks is http://helium.tucc.uab.edu/~sprout/terminal.jpg
I forwarded the bug to the Zvt maintainers, maybe they will know what's wrong.
