Mouse position isn't accurate at the top and bottom of the screen

Help and Feedback Scripting Support

I am making a click effect and to do this I need to find the location of the mouse on the screen. I intend for this effect to happen in the middle of the mouse.
This works fine when I click in the middle of screen as you can see from this image:

But when clicking at the top or bottom of my screen the mouse position seems to be vertically inaccurate as the position is either too high or low:

This is the script I am using to do this:

local userInputService = game:GetService("UserInputService")
local Players = game:GetService("Players")
local player = Players.LocalPlayer
local mouse = player:GetMouse()
local playerGui = player:WaitForChild("PlayerGui")
local ScreenGui = playerGui:WaitForChild("ScreenGui")

local replicatedStorage = game:GetService("ReplicatedStorage")
local mouseParticleTemplate = replicatedStorage:WaitForChild("mouseParticle")

local tweenService = game:GetService("TweenService")

local goal = {}
goal.ImageTransparency = 1

local tweenInfo = TweenInfo.new(
	0.1,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.Out,
	0,
	false
)

local function onInputBegan(input, _gameProcessed)
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
		local mouseParticle = mouseParticleTemplate:Clone()
		mouseParticle.Parent = ScreenGui
		mouseParticle.Position = UDim2.new(mouse.x/mouse.ViewSizeX,0,mouse.y/mouse.ViewSizeY,0)
		mouseParticle.Visible = true
		mouseParticle:TweenSize(UDim2.new(0.055, 0,0.101, 0),"Out", "Linear", 0.1)
		local tween = tweenService:Create(mouseParticle, tweenInfo, goal)
		tween:Play()
	end
end

userInputService.InputBegan:Connect(onInputBegan)

Any thoughts on how I could get the mouse location more accurate?

That has fixed the issues with the position being different at the top/bottom of the screen however now it doesn’t come from the middle of the mouse

I think it has to do with the GUI Inset.

You should account for it when creating the circle.

With the IgnoreGuiInset property set to false its now fine at the top of the screen but at the bottom it still isn’t in the middle.

Along with the GUI Inset as mentioned previously

Try using mouse.ViewportSize instead, the values seem different:
