Just a note that I am seeing this problem as well, here on an AMD 8350
8-core system using Trusty 14.04 AMD64. The Xorg process takes about
20%-35% of one core, when the system is otherwise idle. I'm open to
suggestions regarding how I can dig deeper to determine the cause,

+ Without cpu graph responsiveness is still far slower than with 13.10.
