Comment 12 for bug 409797

Confirm this bug as well. I'm running Karmic with the ATI Proprietary drivers. Xorg CPU usage hovers from 25-75% This is a fresh install of Karmic, not an upgrade from Jaunty. While the computer remains usable, I am experiencing laggy screen draws, including lags when typing in shell windows (through X) between when I type and when the keystroke shows on-screen. CPU usage seems to build over time too. After a fresh login, levels are normal and the system is responsive. Over the course of time, however, usage increases and responsiveness decreases. I'll check to see if it's related to Firefox being open, but FF's CPU usage is "normal"
