RotoPaint nodes will sometimes show a brush stroke that was undone while painting a new stroke.
Customer reported version:
Nuke 13.2v6
Customer reported platform:
Windows 10
Steps to reproduce:
1) Open Nuke and create a RotoPaint node in the Node Graph.
2) View the RotoPaint node, and select the Brush tool.
3) Draw one continuous brush stroke, and then Undo this stroke.
4) Paint another long continuous stroke in the same general area as before.
5) With the mouse button held down, observe the previous stroke exposed underneath the new one. Release the mouse button and it should return to normal.
Expected behavior:
The RotoPaint node should not display any brush strokes that have been undone.
Actual behavior:
The brush stroke that was undone is sometimes visible underneath the new brush stroke. In some instances this happens with the first stroke, or you may have to undo/redo a couple of times. Additionally, it doesn't seem to occur at all in some cases.
Workaround:
Connecting an image to the RotoPaint node's bginput seems to prevent this from occurring.
