This was it. In case anyone else can't find it it's in Media Encoder > Preferences. Change Video Rendering to “Mercury Playback Engine Software Only"

<p>I'm trying to render a video from Adobe Media Encoder, created in After Effects. We first had this problem is a larger file, so I reduced it down to a simple file the results of which can be seen in this gif.</p>

Turn off CUDA rendering, as per [here](http://video.stackexchange.com/q/18405/1871).
