Button's hitbox is offset when building standalone project for two screens



Reproduction steps:
1. Open the attached build of the project named "Build_1141732_New"
2. Select a non-native screen resolution
3. Start the game
4. Move the mouse over one of the buttons on the second screen

Expected result: Button's hitbox is inside the button
Actual result: Button's hitbox is offset

Reproducible with: 2018.3.8f1, 2018.3.12f1, 2019.1.0f1, 2019.2.0a11
Not reproducible with: 2017.4.25f1, 2018.3.7f1

1. The bug only happens when the build is running with a non-native screen resolution
2. This is an existing issue (not a regression) which was masked by another bug:
it preventing setting a non-native resolution and thereby kept this issue from manifesting

    The Unity Editor (2019.4.9f1) works with a second screen (4K) which is of a higher resolution to the primary screen of a MacBook Pro Retina 15", but the game executables do not?

    Surely if Unity has already solved the issue, why can't the solution be applied to the game builds?

    Come on Unity! The workaround suggested by the resolution is NOT USER FRIENDLY!!! It's a really poor and unacceptable workaround!

    Unity is used for not just games but also visualisations, medical and industrial applications! Think about your end-user base please!

    What kind of workaround is this? "To work around this problem with Multi-Display, ensure all display have the same Resolution or screen size." Let me just ask all users to buy new monitors.

    Same problem here. Using ScreenSpace - Camera does not help either.

    We're having the same problem right now with ui controls (buttons, sliders, dropdowns) not receiving their raycasts when on a secondary display which has a different resolution than the first one.

    We are also experiencing this issue, it's making multi-monitor projects difficult to work on.

    I confirm this nasty problem, it is highly problematic on multi-display Windows system with different resolutions.
