I believe that this bug is not tied to Nvidia, which may mean that it not a duplicate of bug #877438.

I can confirm the bug on an multi headed Intel i7 system with an ATI Radeon HD6670.

Any gnome-terminal window that scrolls will slow down the entire desktop to crawl. Up to several seconds of delay when typing in another window.

I have tried tha various drivers including the xorg radeon driver from Oneric, the xorg radeon driver from the xorg-edgers PPA, the fglrx driver from Oneric and the latest fglrx driver from AMD. I have 3 active displays when using the radeon driver and 2 when using the fglrx driver. The bug is clearly present using any of these configurations.

I have also tried both the Gnome and the Unity desktops (all modes). They all have the same problem!

I used to have a window showing the live logs from my log server. In 11.04 this will makes my workstation completely unusable. The same setup on the same hardware was extremely fast and responsive when running 11.04.

I do not see the bug if I use an xterm for the scrolling window.

The problem is clearly not specific to neither Nvidia or a single display driver. It is most likely tied to the compiz and multi-head combination.
