Problem summary VectorDistort has no viewer output when setting blur size between 22.307687 to 22.307694
Customer reported version nuke._12.0v5
Customer reported platform centos7
Steps to reproduce
1) Open Nuke
2) Read in footage
3) Create a SmartVector node and attach footage
4) Create a VectorDistort and connect to the SmartVector node and footage
5) Make sure the VectorDistort Output is set to "warped src"
6) Change Blur in VectorDistort to a number between 22.307687 and 22.307694
7) The result should have no viewer output from the VectorDistort node
Expected behaviour For the VectorDistort to apply the blur based on the number being input
Actual behaviour Having Output set to "warped src" and inputting a number between 22.307687 to 22.307694 causes the viewer to output nothing
Workaround As an alternative to using the "warped src" select the "st-map" and use that as the base for your distortion.
