New Input system mouse returns wrong values
I've been trying to use the new input system to allow both mouse and game-pad to control where thruster is located around another object (Blaster game object) based on the direction to a target rotating around a pivot (Similar to this but instead of rotating in object space it should rotate in world space around a point: 
)
It all works fine when as target I use another game object's in the world the rotation works perfectly (see below) https://youtu.be/jzZpOynPUZY
but when I switch to use the mouse position as the target a nasty glitch happens when the mouse is around 45° from the main pivot object (see below) https://youtu.be/Sxip_k23GEU
I can't say it only happens when cursor is at 45° as sometimes it also happens just around 85° (so I would constrain this problem to the first quadrant)
This is how I achieve this, but I can't seem to find the issue with my code as I have confirmed the raw values received by the mouse are incorrect at times.

if (aimDirection.x > 0f && aimDirection.y > 0f)
{
var gamepad = Gamepad.current;
var mouse = Mouse.current;
if (gamepad != null)
{
aimDirection.Normalize();
}
else if (mouse != null)
{
Vector3 screenSpaceMousePos = new Vector3(aimDirection.x, aimDirection.y, -Camera.main.transform.position.z);
Vector3 worldSpaceMousePos = Camera.main.ScreenToWorldPoint(screenSpaceMousePos);
Vector2 mousePos = new Vector2(worldSpaceMousePos.x, worldSpaceMousePos.y);
Vector2 pivotPos = new Vector2(pivot.position.x, pivot.position.y);
aimDirection = mousePos - pivotPos;
aimDirection.Normalize();
}
#else
Vector2 targetPos = new Vector2(target.position.x, target.position.y);
Vector2 pivotPos = new Vector2(pivot.position.x, pivot.position.y);
aimDirection = targetPos - pivotPos;
aimDirection.Normalize();
#endif
var inverseOrbit = aimDirection * -radius;
transform.position = inverseOrbit;
if (lineRenderer && lineRenderer.enabled)
{
lineRenderer.positionCount = 2;
lineRenderer.startWidth = 0.3f;
lineRenderer.endWidth = 0.3f;
lineRenderer.SetPosition(0, pivot.position);
lineRenderer.SetPosition(1, inverseOrbit);
}
else
Debug.LogError("noLineRendererFound");
#if INPUT
}
else
{
Debug.LogError($"the aim direction goes negative!! [{aimDirection.x},{aimDirection.y}]");
Debug.LogError($"Previously was [{previousAimDirection.x},{previousAimDirection.y}]");
}
previousAimDirection = aimDirection;
#endif
}
private PlayerInput _playerInput;
private InputMaster _controls;
}
Has anyone got any idea why this is happening?
