On 2019.1 Windows, some of the input have a delay for it to be registered, like button press, stick movement, etc. Sometimes, it is delayed so much that the button seems never pressed or stuck.
This could be a perf issue only happens on 2019.1

Repro:
1. Download the GitHub project: https://github.com/Unity-Technologies/InputSystem/tree/develop
2. Go to Assets -> QA -> Input_Test -> Scenes -> 02_Input
3. Enter Playmode in Editor and observe how it works with keyboard & mouse.
4. (optional) Go to Assets -> Demo -> SimpleDemo -> SimpleDemo scene
5. Enter Playmode and try to shoot by clicking left mouse button
6. Observe the shooting pattern.

Expected: there is no delay in detecting any input with ISX
