Bug Description
Binary package hint: xorg
Opening the Gnome Terminal, and scrolling a large file, e.g. 'dmesg | less' and pushing the DOWN key shoots Xorg to almost 100% CPU and becomes very slow.
This wasn't happening with Ubuntu 10.04. Also, it is not related to Compiz it seems, as it happens with compiz turned off.
Let me know how I can help.

Why nVidia?
As far as I remember (I'll have to retest) the problem does not go away when I downgraded.
