IPointerEnterHandler & IPointerExitHandler are seemingly unprecise

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:

Code (CSharp):

1.     public void OnPointerEnter(PointerEventData eventData)
2.     {
3.               Debug.Log(currentHover.name + " @ " + ReInput.controllers.Mouse.screenPosition);
4.     }
5.  
6.     public void OnPointerExit(PointerEventData eventData)
7.     {
8.        Debug.Log("Exitted");
9.     }
10.  

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.
