Gnome-terminal works just fine when I am running Unity, but when I run Gnome shell, terminals don't work properly and have to be constantly refreshed. This is particularly annoying when using "vi" to edit text files. In the old, old days, I saw problems like this when the ".profile" file didn't have the correct setting for TERM. But I thought that modern distributions had pretty much solved this issue.
In anyone else seeing this behavior? Hard to believe that it's only me with this problem.
For what it's worth, I have this issue on every one of my four Ubuntu 11.10 installations, so I know it's not a hardware issue.
