(Get the code!)
I can also confirm this bug. Running on kernel 3.16.0 with the amd catalyst driver gala is always using at least one of four cpus. On a live usb stick this doesn't happen, so I guess it's caused by the proprietary driver.
I can temporarily fix the cpu consumption by killing gala and restarting it again (made a keyboard shortcut for it). Doing this gala only needs 1-5% of the cpu (instead of 25-30%). I'm going to try Thomas' solution now and report back.
