You're slightly overloading your GPU. Might not be a big issue for you, depending.

Your network connection is also being overloaded. This may be related to your problem with stalling incoming video feeds from browser sources. Later in the log, OBS is unable to reach Twitch at all:

This log seems to indicate a failure to load a Mixer source, but it does not say why. I have regularly used Mixer feeds in a browser source; given the other network related errors in your log, your connection may be the cause.
