ID 214902 - Filter Size on F_WireRemoval node does not effect the result on Windows or Linux

Problem summary
The F_WireRemoval node Filter size behaves differently on Mac than on Windows and Linux. On Windows and Linux adjusting the Filter Size appears to do nothing, when compared to the same scene on a Mac, where it helps clean up distortion caused by the F_WireRemoval node.

Customer reported version
nuke.10.0v1

Customer reported platform
centos6

Steps to reproduce

1) Open Nuke

2) Create a Read node and read in the attached clouds tiff sequence.

3) Create a F_WireRemoval node, and connect the source input to the Read node

4) Line the F_WireRemoval node​'s overlay with the top wire, as shown below. 

5) Set the Output to repair, and adjust the Filter Size. On Mac this helps alleviate the distortion, but on Windows/Linux is does very little/nothing. Below are examples on Windows and Mac

Left image​, Filter Size = 5, Right image​, Filter Size = 100, both screen shots on Windows
​

Left image​, Filter Size = 5, Right image, Filter Size = 100, both screen shots from Mac

Reproduced by support
I found that Filter Size has no effect on:

Nuke 8.0v6 Linux CentOS 6
Nuke 9.0v1 Linux​ CentOS 6​
Nuke 9.0v8 Linux​ CentOS 6​
Nuke 10.0v1 Linux​ CentOS 6​
​
Nuke 8.0v6 Windows 10
Nuke 9.0v1 Windows 10​
Nuke 9.0v8 Windows 10​​
Nuke 10.0v1 Windows 10​

But the Filter Size does make a difference on:

Nuke 8.0v6 Mac OSX 10.11
Nuke 9.0v1 Mac OSX 10.11​
Nuke 9.0v8 Mac OSX 10.11​​
Nuke 10.0v1 Mac OSX 10.11​

Expected behaviour
For the Filter Size to effect the output result

Actual behaviour
It didn't make a difference on Windows or Linux machines.
