1191036

Regression

Yes

Screen.dpi is not consistent in the Editor when using multiple screens with different dpi scalings

IMGUI

-

Reproduction steps:
1. Make sure to have screens with different DPI scalings
2. Open the attached project named "Case_1191036"
3. Enter Play mode
4. Click between Unity windows in different screens
5. Observe the console window

Expected result: dpi reports consistent dpi reading
Actual result: dpi is changing whenever the mouse is moved inside one of the windows

Reproducible with: 2018.2.0a6, 2018.4.12f1, 2019.2.11f1, 2019.3.0b9, 2020.1.0a11
Not reproducible with: 2017.4.34f1, 2018.2.0a5

Notes:
To reproduce the issue monitors with different resolutions can be used (4k and 1080p). If monitor resolution is the same, changing the Windows DPI settings for one of the screens will also reproduce the issue.

  1. Resolution Note:

    Since high dpi support was introduced in 18.2, Screen.dpi contains the dpi value for the last window that was rendered.
    When the game runs, it's constant since the game has only one window, however, in the editor, you might see changes in value like this.

    The only time You can be assured that Screen.dpi (or EditorGUIUtility.pixelsPerPoint) are referring to the current GameView window's dpi scaling values is during the OnGUI() method.
