Problem summary
The Viewer outputs a grey image when there is an IDistort downstream of a time node
Customer reported version
Nuke 13.1v1
Customer reported platform
Linux
Steps to reproduce
1) Open Nuke and create a Checkerboard node.
2) Create a AppendClip node and attach the Checkerboard node into the AppendClip node.
(This also happens with other time nodes including Add 3:2 Pulldown, Remove 3:2 Pulldown, FrameRange, TimeOffset and Vector to motion)
3) Create a IDistort node and attach the Checkerboard node to the IDistort node.
Expected behaviour
For the Viewer to display the attached image
Actual behaviour
The Viewer outputs a grey image
Workaround
Adding a node upstream of the IDistort node displays a corrected behavior.
Also discovered, changing the filter knob of the IDistort node to 'impulse' removes the gray image in the Viewer.
