Problem summary When cloning using the RotoPaint node, if the source footage is of a resolution that uses an odd number, when painting the cloned area, it will progressively deteriorate and soften per every iteration.
Customer reported version nuke.11.2v5
Customer reported platform windows10
Steps to reproduce
1) Create a Checkerboard node
2) Within the properties of the Checkerboard node, create a new resolution within the 'format' knob of 2001 x 1001 and name it 'A'
3) Create a RotoPaint node under the Checkerboard node
4) Select the 'Clone' tool and use the yellow crosshair of the Checkerboard node as the source for the clone, cloning to a new area to the right. Result: Clone result is softened
5) Clone the cloned result Result: Further softening occurs
6) Repeat steps 2- 5 using a Checkerboard with a resolution of 2000 x 1000. Result: No softening occurs
Expected behaviour When cloning from a source image degradation or softening should not occur
Actual behaviour When cloning from a source image degradation or softening occurs when using a resolution source that has an odd number.
Workaround Unknown. Avoid using odd numbers within the resolution source if cloning using the RotoPaint node.
