IPointerEnterHandler & IPointerExitHandler are seemingly unprecise

Unity Engine

Hi!
I am making a pixel art game, so every little pixel counts.
I have made a Hover and HoverExit function utilizing Rewired for the GameObjects and it works flawlessly, down to the tiniest pixel.

However, problems occur when I am trying to make similar code, but for UI objects instead.
I have 2 buttons lined up next to each other, few pixels apart, and the buttons are not overlapping.

Despite this, if I happen to have an OnPointerEnter called on either of these buttons, and I move the pointer to the other button, the OnPointerExit will not be called.

I got my code all the way down to this:

    public void OnPointerEnter(PointerEventData eventData)
    {
              Debug.Log(currentHover.name + " @ " + ReInput.controllers.Mouse.screenPosition);
    }

    public void OnPointerExit(PointerEventData eventData)
    {
       Debug.Log("Exitted");
    }

And I can see in the log, that the OnPointerExit is never called on this scenario.
If I hover a button, and then stop hovering it, the OnPointerExit will be called, but not when i hover Button 2 after hovering Button 1.

My buttons look like this:

The yellow image has Ignore Raycast on.
Am I just missing something? Or is there a different, more precise way to check for UI raycast?

To anyone else, use raycasting.
This issue with iPointerHandlers has been unfixed for more than two years - I found a reddit thread exploring the same issue, and used the solution from there. Raycasting works perfectly.

Im having the same issue now, what did you do by ‘use raycasting’?

iPointerHandlers arent returning expected for hovering UI elements so I am trying to code whatever it does, but do it myself, presumably with raycasting.
