tyselect - curvature flickering with vertex color

[nayan]

hey there, when I convert the tyselect curvature to vertex color, the dark areas flickers a lot continously(especially when fall off is assigned).....while if the same thing I do with data channel curvature, its super smooth.....

How can I stop flickering in curvature

Here's an attachment showing the difference in curvature selection.....left is data channel and right is tyselect. you can clearly see the difference in smoothness...
