 * There is a bad interaction with the high resolution peak screen that makes links not work properly. Install all the patches from here: https://bugzilla.mozilla.org/show_bug.cgi?id=883646. Note that the first 7 of these have already landed on m-i, so you may only need the 8th depending on when you update and which tree you are on.
-* The patchsets at: https://github.com/YiyiLee/webrtc-perf-patches should get WebRTC working. However, because the Peak has more CPU, you do not need as aggressive tuning. A new patchset is coming shortly.

 WARNING: This is mostly working. I still get occasional warnings about corrupted stacks. As soon as this problem is solved, I will update the instructions here. --bbrittain
