Problem summary
F_Regrain produces unexpected results when used in conjunction with aspect ratios greater than 1. Customer reported version
nuke.11.0v3
Customer reported platform
10.11
Steps to reproduce
1) Launch NukeX and open the attached script.
2) Connect your viewer to the output of Crop1 and view the broken result.
Workarounds
Workaround 1:
1) While still viewing the broken result disable the "Crop2" node and proceed to play the footage. Enable the Crop1 node and now the result will display the grain inside of the cropped output inside of the larger aspect ratio.
Workaround 2:
1) Reformat the crop node so that it fills the format of the project.
2) After the f_Regrain node create a Transform with a center of (0,0)
3) Translate the linked X and Y of the Crop node so that it is repositioned in its original place.

Earliest version tested
NukeX7.0v10
Expected behaviour
Nuke would be able to apply the grain to the cropped footage.
Actual behaviour
Nuke is unable to apply the grain to the cropped footage without causing errors within the Viewport. However this can be circumvented by cropping the footage after the grain has been applied.
