Hi Adrien, This can be rather difficult to find the cause of; I've seen it once on one of my machine, and it turned out to be an application I was using that was doing a lot to the X server for no good reason. (It was animating a little icon but was trying to be too clever).
Run top and watch what is taking the cpu, then close each application and see if it drops, to try and find out what is using the cpu.
