EXR Deep ObjectID Bugs

Hello Developers,

it seems there are few malfunctions in Maxwell Renderer (3.1.00) in deep exr processing. They occur in Object id, which then affects all other channels and makes post-compositing in Fusion/Nuke impossible.

Illustrations and how the errors appears:
1) create a scene with 10 spheres which are in a row from camera toward distant point in the scene

2) render using default parameter + deep exr
(here is the scene and the output EXR image file)

3) load into an application or read the exr data out: use picker to detect the Z values of the pixels between the spheres. On each edge around sphere there is an anomaly

The complete DeepExr ist with it unusable, since post-processing creates ugly pixels with DOF, Fog etc.
best regards
