Strange Problem/Artifact When painting Textures on top of each other on a terrain

Question

When painting textures together on a terrain, sometimes I get this strange effect where the paint on the borders of the brush will cause lighter sections. I've included a picture where you can see the lighter parts on the border of the green patch.

It doesn't seem to happen with all texture combinations, and all my texture layers have the same size and offset. Also, the picture shows the effect on a raised surface, but when I paint off the raised surface, on a more flat surface, it still happens. I'm using textures out of the standard assets package. Can anyone please tell me what's going on?

As a temporary measure Switch to a brush without falloff

I had this issue for 2-3 days at this point.

I fixed it by updating from Unity 2018.4.21f1 to Unity 2019.4.6f1

NOTE1: I am on Unity 2019.4.0f1 and experienced this on only one of a few maps.
NOTE2: It is always best to back your project up and have a place to revert back to.

SOLUTION: On your infected terrain, simply do the following:

Select 'Terrain' object and Select 'Terrain Settings' (Gear Cog Icon)
Scroll down to "Texture Resolutions (On Terrain Data)"
Modify your 'Control Texture Resolution' setting. (I personally was already set to 1024x1024 and changed it to 2048x2048 and then reverted back to 1024x1024).
You may get a console error: Failed to create Object Undo, because the action is too large. Clearing undo buffer

This is not a problem overall and your terrain textures should still be present and you should be able to paint without the artifact.
