Problem summary
Viewing a TimeBlur, with 1 division or 0 shutter duration, and changing its shutter offset value will adjust the bounding box.
Customer reported version
Nuke 13.1v1
Customer reported platform
ubuntu
Steps to reproduce
1) Open Nuke.
2) Create a Roto node and draw a shape in the Viewer. Set the output knob to rgb, so you can see the shape in the Viewer.
3) Create a Transform downstream from the Roto.
4) Right click the rotate knob > Add expression... > enter the following expression:
(frame%1)*360
5) Create a TimeBlur node downstream from the Transform.
6) Set divisions to 1 and shutter to 0.
7) Set shutter offset to custom.
8) With the TimeBlur node attached to a Viewer, move the shutter offset slider back and forth.
Expected behaviour
When the division knob is set to 1, and shutter is set to 0, changing the shutter offset does not affect the image. In this case, the bounding box should not change either.
Actual behaviour
Viewing a TimeBlur, with 1 division or 0 shutter duration, and changing its shutter offset value will adjust the bounding box.
Workaround
Unknown.
