Latitude 7480 DualPoint Stick - difficult to move cursor diagonally

Hello I am on a journey to replace windows with linux and I have settled with Opensuse and Endeavouros.
But I have one issue with my DualPoint Stick that it is difficult to move the cursor diagonally.
Plus the cursor is really slow setting it with kde settings unless using adaptive acceleration making it even harder to move the DualPoint Stick with any accuracy.

For example if I want to move the cursor diagonally “up a bit to the left”, it create a jagged path of vertical and horizontal movements and end up missing the target with a few pixels.

If I drag the DualPoint Stick a bit harder I can make a diagonal line but not ideal when trying to select text or moving in a fine line.

I opened gimp and made a drawing to show how the cursor act:

I am not one bit familiar what any of these values does or how to change them.
Are there any parameters that could aid this?

The only distro that has been marginally better is Elemetary OS.
It is a little easier to get the cursor going in a diagonal line even though the does move with jagged lines if I move it slowly

Not saying this is the reason, but I wonder if it could be a similar “feature” to the X230 trackpad (also seen on similar Thinkpads).

This responds in steps (almost “grainy” rather than smooth) because it’s supposed to make it “easier to use” by limiting small movements (e.g. when you wobble the tip of your finger side-to-side on the pad).
