I think we would need a stack trace of the problem. Please do: 1. Apply the workaround from bug 994921. 2. Open a terminal or log in to another VT (Ctrl+Alt+F4). 3. Reproduce the high CPU problem. 4. While the problem is occurring, run: killall -ARBT `pidof -s gnome-shell` 5. Look in /var/crash for the crash file. 6. Create a new bug using this command: ubuntu-bug /var/crash/YOURFILE.crash 7. Tell us here the ID of the new bug.
