Virtual joystick and resolutionScalingFixedDPIFactor problem

Hey, I am trying to use a virtual joystick and also have implemented some downscaling factor for resolution in my android game.

The problem is that when i use any factor lower then 1f my joystick is not working anymore. It just pops and sticks to the left edge right when i touch the screen.

 QualitySettings.resolutionScalingFixedDPIFactor = 0.9f;

The virtual joystick scrips are the following:

 using UnityEngine;
 using UnityEngine.EventSystems;
 
 public class Joystick : MonoBehaviour, IDragHandler, IPointerUpHandler, IPointerDownHandler
 {
     [Header("Options")]
     [Range(0f, 2f)] public float handleLimit = 1f;
     public JoystickMode joystickMode = JoystickMode.AllAxis;
     public Transform camera;
 
     protected Vector2 inputVector = Vector2.zero;
 
     [Header("Components")]
     public RectTransform background;
     public RectTransform handle;
 
     public float Horizontal { get { return inputVector.x; } }
     public float Vertical { get { return inputVector.y; } }
     public Vector2 Direction { get { return new Vector2(Horizontal, Vertical); } }    
 
     public virtual void OnDrag(PointerEventData eventData)  {      }
 
     public virtual void OnPointerDown(PointerEventData eventData)  {      }
 
     public virtual void OnPointerUp(PointerEventData eventData)  {       }
 
     protected void ClampJoystick()
     {
         if (joystickMode == JoystickMode.Horizontal)
             inputVector = new Vector2(inputVector.x, 0f);
         if (joystickMode == JoystickMode.Vertical)
             inputVector = new Vector2(0f, inputVector.y);
     }
 }
 
 public enum JoystickMode { AllAxis, Horizontal, Vertical}

and:

 using UnityEngine;
 using UnityEngine.EventSystems;
 
 public class FixedJoystick : Joystick
 {
     Vector2 joystickPosition = Vector2.zero;
     public static bool isPressed = false;   
 
     void Start()
     {
         joystickPosition = new Vector3(transform.position.x, transform.position.y, transform.position.z);
     }  
 
     public override void OnDrag(PointerEventData eventData)
     {
         Vector2 direction = eventData.position - joystickPosition ;
         inputVector = (direction.magnitude > background.sizeDelta.x /2f ) ? direction.normalized : direction / (background.sizeDelta.x / 2f);
         ClampJoystick();
         handle.anchoredPosition = (inputVector * background.sizeDelta.x / 2f) * handleLimit;
         isPressed = true;
     }
 
     public override void OnPointerDown(PointerEventData eventData)
     {
         OnDrag(eventData);        
     }
 
     public override void OnPointerUp(PointerEventData eventData)
     {
         inputVector = Vector2.zero;
         isPressed = false;
         handle.anchoredPosition = Vector2.zero;        
     }
 }

I would like this explained, as I am not looking for someone to just edit the posted code. I appreciate the help!
