I thought of something that might explain the mystery: Do you happen tohave transparent background enabled in gnome-terminal?
Nope, the original configuration, I didn't change anything from the default config.
How is the resize performance of the two kinds of gnome-terminal windows after you kill and restart compiz?
Did a killall compiz.real, which restarts it. The behaviour is the same as before : the first terminal is ok, the second one is sluggish. I also tried to restart gtk-window-decorator which didn't change anything.
