UI Sliders on secondary screens do not respond correctly when using Multiple Displays



Reproduction steps:
1. Open the attached build of the project named "Build_1146233"
2. Move the slider on the first screen. Slider functions properly
3. Try to move the slider on the second screen

Expected result: Slider behaves the same way as in the first screen
Actual result: Slider is broken and instantly turns into max value

Reproducible with: 2017.4.26f1, 2018.3.13f1, 2019.1.0f2, 2019.2.0a12

1. The behavior of the slider depends on Windows positioning of the monitor. When setup is like in Snapshot_1146233_V1 behavior is as shown in Track_1146233_V1. When setup is like in Snapshot_1146233_V2 behavior is as shown in Track_1146233_V2.
2. Testing is hampered in 2018.3.8f1 and above due to another issue ( case 1141732 ).
3. The issue also happens when Scrollbar or Scroll View UI components are used.

    The issue is still not fixed in Unity 2017 (tested version : 2017.4.34f1) !
    Please fix it or remove wrong information on this page.

    We're also having this issue and it's hindering us from delivering an app to a client. Plz fix this! :)
