Draft assembly job produces an image with black lines

This problem seems to have been fixed I think since Deadline 10.0.10.3, at least we didn’t see the problem since we updated back then, however recently when we just updated to Deadline 10.0.18.1, we started getting the same issue again…
This is an image rendered in 6000x2394 and it has the black lines

This one is rendered at 6000x3380 and no black lines

Both of them were rendered in 5x5 tiles
So it’s safe to say that the problem is the same as before.
Here is the testing scene file : still_test_v16.zip (13.8 KB)

Should I roll back to deadline 10.0.10.3 again for more testing ? Any idea why this bug fix would disappear in the Deadline 10.0.18.1 ?

EDIT : reverting back to the 10.0.10.3 version of SubmitMayaToDeadline.mel seems to have fixed the issue, the above image doesn’t have lines anymore.
