    Can anyone confirm:
    • create new project
    • create new scene
    • add button
    • save scene
    • build to standalone
    • run game in full screen on non-native resolution
    • try to press the button; will fail
    • click around the button, will likely succeed
    • run again at native resolution, pressing button will work as expected
    • hit tests as expected in Unity 4, not in Unity 5.1.2

    In Unity 4 you'd get black bars if game aspect ratio doesn't match the monitor's aspect ratio.

    In Unity 5 and Direct3D11, when you choose for example 640x480 from the game launcher on a monitor with a different aspect ratio, the screen will be extended to fill the physical monitor and eliminate any black borders. Unfortunately in this case the math is off for the mouse position.

    Does anyone know of a workaround for this? Been bothering me while learning how to utilize UI.

    In the Editor it works OK. In the build, keep the same aspect ratio as the desktop, preferably the same resolution. Otherwise disable D3D11.
