Mouse's Y position inconsistent when positioning gui to it

Hi, I have an inventory script where players drag around inventory items I’ll let you see the problem here. Notice how the gui’s Y position changes as the mouse position goes lower.

UI Testing - Roblox Studio 2022-07-23 23-57-32 (Video is messed up sorry)

I am using a heavily modified version of this script so here are the most important parts. How To Make A Draggable GUI? - #9 by MrchipsMa

local function update(input, gui)
	local delta = input.Position - dragStart
	gui.Position = UDim2.new(startPosX, -1.5 + delta.X, startPosY, delta.Y)
end

--later in the script
startPosX = mouse.X/mouse.ViewSizeX
startPosY = mouse.Y/mouse.ViewSizeY

I am parenting the GUI to the ScreenGui which in which it doesn’t matter whether IgnoreGuiInset enabled or disabled.

I just want it to go a little left of the mouse and while the startPosX works, the startPosY is just not working.
Thanks!

This is the X Scale, not the offset. Change this to offset and make sure the scale is positioned at 0, 0.

I recommend not finding the start position of the mouse, and the GUI instead. This is what the scale should be.

Yes I know that’s why I made the mouse position into scale using viewsize. If I use the GUI’s position it won’t snap to where I want on the mouse that’s why I want to use the mouse’s position.

If I similarly use basically this same script with different offsets for my mouse hover position it works perfectly. That’s why I’m confused.

Tried it slightly your way leaning more on offset and I found a way that makes the position change so minor it’s unnoticeable thanks!
