the stop line being partly white and partly blue

I am not sure if I understand the question.
What is a "stop line"?

Chromatic aberration does not happen at image center.
So, you may check if the issue happens just around image corners or also at image center.

In general, line artifacts could be due to over sharpening, demosaicing, or WDR back lighting.

Hi Gang, 

The 'stop line' refers to this:

What is your suggestion on solving this problem? less Edge sharpening or modifying demosaicing?

Thanks Adam!

I now understand the issue.
While that white line is far away, it may appear as green or yellow occasionally.

It seems related to color aliasing, white balance and demosaicing rather than chromatic aberration.
Is it possible to share some raw/yuv images so that we can reproduce the issue?

Please fix the white balance issue (road payment looks green) first if possible.
