We just had similar issue, with artifacts in random frames using ZDefocus. Very
hard to debug.
In our case the artifacts were triggered by large depth differences and
appeared in same place. Reducing depth difference in these places removed
artifacts completely.
Hope it helps.

Yes, kind of. (it has limitation like sample 1 only)
Create card, Scanlinerender with your camera. Normal 3D setup. Right after
scanlinerender place deepToImage. This will convert your 3D render into Deep.
The deep will be matched to your Maya renders.
Let me know if you have questions.
Cheers,
