The Y value for the mouse position of the new Input System is incorrect. The 0 is supposed to be at the bottom, but it is reversed in the Editor.
The X value uses the same 0 point. But as the cursor moves farther away, the difference in value gets more noticeable.
ONLY in Linux Editor. NOT in Standalone Player.

Repro:
1. Pull Github Project from: https://github.com/Unity-Technologies/InputSystem/tree/develop
2. Open Scene in: Assets -> QA -> Input_Test -> Scenes -> 02_Input
3. Enter Playmode in Editor
4. Call out the More Information menu on the side
5. Compare the mouse position between the old and the new.

Expected: The mouse position is consistent between the old and the new Input System.
