Excessive CPU usage in Ubuntu 14.04 with GNOME 3 & Xorg

[thomasokken]

I just tried building and running the latest from GitHub in a VM running Ubuntu 14.04, and I found that it was dropping mouse events as well, and also just being unbearably sluggish overall. I noticed that while the app was running, compiz was running at over 100% CPU, and xorg was using another 40% or so. Compiz pegging a core could explain the dropped events.

Note that this version does include the -std=gnu99 option that was mentioned earlier... it also includes -no-pie in src/makefile, which I had to remove because it was not recognized, and causing compilation to fail.
