This is a fairly important bug that has been around a while.

I am noticing it seems to only flip the Y in the browser. and that flipped value will remain until the mouse is moved again.

example:

  void Update()
    {
        if (Mouse.current != null)
        {
            print(Mouse.current.position.ReadValue().y);
        }
    }

bottom of screen = 0
top of screen = screen height.

use scroll wheel without moving mouse

(flipped y values)
bottom of screen = screen height.
top of screen = 0

• move mouse again...mouse goes back to normal values.
• X always stays correct

I wrote a method to track and flip the Y when its "dirty" from the scroll wheel and not yet moved. but if you move the mouse and scroll at the same time quickly it still gets wacky.
