Stop Media Encoder Compositing error? - HELP!

Question

I am queing a sequence from Premiere Pro CC to Media Encoder. Its a composite of a subject on a green screen keyed background with some slide overlays.
When the sequence is rendered there is an odd 'cropping' effect on the slide portion of the video.
Where it should look like this
This happens throughout the entire sequence, in multiple sequences. There is no crop effect of any kind applied to the footage, the entire sequence will play out just fine from inside the timeline, the effect only shows up when rendered through AME.
When I stop AME from using OpenCL and render using Software only the problem appears to be resolved. But I definitely don't like the idea of investing so much CASH in GPU acceleration if Encoder can't effectively take advantage of it. Frustrating.
Anyone seen familiar with a fix for this kind of problem!? Thanks

Answer 1

This began happening to me after a recent update to my AME CC version.  I found that I could rendered directly from Premier Pro CC through the export function. 
It apparently has to do with 3-d memory adresses.   I was doing a scene with talent over a keyed out green screen and a CGI stage set in the background.  About two thirds of the background was not rendering, even after I made sure the size requirement for the graphic elements was correct.
I would be interested incomments from someone at Adobe about this situation, we cannot be th eonly ones.
Oh, I am running hardware acceleration on the open GL and have 18 gigs of memory on the motherboard.  3.2 GHZ eight core procesor.
