Xubuntu's default terminal emulator performs like a DOS window in Windows 3 on a 286. You can see the individual lines being refreshed from top to bottom when scrolling. And when dragging the window around, the repaints are much slower and jerkier than for any other app I've tried. xterm is far faster.
