If you are using Ubuntu and are experiencing dropped frames or system lockups while streaming/recording, and you are using the full screen projector to display the results on a second monitor, then you may be running into an xserver-xorg compatibility issue. Details are in this bug report thread.

In summary, if you are installing any customized or optimized kernels/xservers, you could run into the exponential CPU usage issue. Certain configurations seem to cause problems with xserver video drivers, that will gradually increase the cpu usage to the point where the system will crash or start dropping frames.
For Ubuntu 16.04 it is best to stick with the base xserver-xorg-core package and related video drivers. In my case this was xserver-xorg-core 1.18.4 and xserver-xorg-video-intel packages. Once making sure I had these items in place, I was able to use the full screen preview without issue. Hopefully this helps others that may be experiencing this problem.
