ID 305967 - DeepCrop node causes bbox cropping when viewing/rendering through Write node in a stereoscopic workflow

Follow

Problem summary
When you add in a 'DeepCrop' node that has expressions added in the crop value knobs (within a stereoscopic workflow) then view/render it out via a 'Write' node, the 'Write' node will crop one of the views (usually the right view) to an incorrect size bbox.

Customer reported version
nuke.10.0v5

Customer reported platform
centos6

Steps to reproduce

1) Open Nuke, load in a stereo Read node and associated DeepRead.

2) Beneath the DeepRead, add a DeepCrop with "bbox" knob expressioned to:
"input.bbox.x", "input.bbox.y", "input.bbox.x + input.bbox.w", "input.bbox.y + input.bbox.h"

3) Connect the Read node and DeepCrop with a DeepRecolor.

4) Add a DeepToImage and a Write node.

5) Set your view to "right" and toggle between the DeepToImage and Write node in the viewer
Result: Bbox is cropping the right stereo image in the Write node

Workaround
Unknown.

Reproduced by support
This problem has been reproduced on:

Nuke 11.0v1 - CentOS 6.9 - Windows 7 - MacOSX 10.12
Nuke 10.5v5 - CentOS 6.9
Nuke 10.5v1 - CentOS 6.9
Nuke 10.0v5 - CentOS 6.9 - Windows 7 - MacOSX 10.12
Nuke 10.0v1 - CentOS 6.9
Nuke 9.0v9 - CentOS 6.9
Nuke 9.0v1 - CentOS 6.9
Nuke 8.0v7 - CentOS 6.9 - Windows 7 - MacOSX 10.12


Earliest version tested
Nuke 8.0v7, as earlier releases do not have the functionality to use Bbox values as expressions.

Expected behaviour
The Bbox should have not cropped the left hand side of the right stereo view

Actual behaviour
The Bbox crops the left hand side of the right stereo view
