ID 159305 - The Median node or Transform with motionblur causes Nuke to freeze/ hang on Windows.

Problem summary
The Median node and Transform with motionblur cause nuke to freeze/ hang on Windows.

Customer reported version
nuke.12.1v2

Customer reported platform
windows10

Steps to reproduce

1) In Nuke, create a Checkerboard node.

2) Add a Median node.

3) View the Median node, and as it's processing in the Viewer, do another action like scale the Size knob.

Expected behavior
Nuke should continue processing the Viewer actively and not allow a whitescreen freeze/hang.

Actual behavior
Nuke hangs or displays a whitescreen/freeze while processing the Viewer.

Workaround
Reducing the thread count that Nuke uses with the -m flag helps to mitigate some of the hanging.
