[Input System] Mouse.current.position value is offset by 1 pixel compared to old system's Input.mousePosition



Steps to reproduce:
1. Open the attached project (
2. Enter Play Mode
3. Move your mouse around

Expected result: Mouse coordinates of the new Input system match the old system
Actual result: Mouse coordinates of the new Input system are always offset by 1 pixel in either Dimension

Reproduced in: preview-0.2.6 (2019.3.3f1), 1.0.0-preview.5 (2020.1.0a25)
Cannot test with: preview-0.2.1 and earlier (Assertion failures)

- The issue is reproducible in both the Editor and Player
- If the mouse cursor is placed in any corner of the window, the positions reported match
- If the left mouse button is clicked, the coordinates reported by the new Input system are "snapped" and match the old system's
- If the mouse is "flicked" and quickly lifted, the new InputSystem will incorrectly report its position
