This bug affects my installation of Natty as well when running in the No-effects version session. It happens with many programs, not just gnome-terminal.
Enabling composting in metacity or using compiz fixes the issue, but adds visual candy that I dislike and seems to also cause occasional GPU hangs (already filed in another bug report). So I do think this is a metacity issue; however, I have the same behavior when using Openbox as my window manager in gnome, which may or may not be related.
