Improving movement along diagonal walls (grid graph)

Hello!

I tested the different types of graph for my game and considering that my game is a TD + RTS formula, I’m using a grid graph. I’d really rather not use a RecastGraph.

My walls are: vertical, horizontal and diagonal (they are all angled by 45 degree increments).
My units move smoothly when they go against vertical/horizontal walls since they follow the tiles of the grid. However, when they’re going along a diagonal walls, it’s can easily result in a jagged movement where they go back and forth.

I thought putting the grid graph’s connections to 8 would solve this, but it doesn’t… I don’t think this setting does anything with FollowerEntity?
Anyway, my question is:
Is there a way I can improve movement along the diagonal walls, considering I only have this limited types of angled walls in my game?
I’m using the FollowerEntity movement on my units.
