Regression

Yes

Editor freezes for a moment when moved from one screen to another with different resolution scale

Themes

-

How to reproduce:
1. With a two-screen setup change one of the screen's resolution scale so they would be different (right-click on desktop->Display Settings->Scale and layout)
2. Create a new Unity project
3. Drag the Editor from one screen to the other

Expected results: The Editor does not freeze at all
Actual results: There's a short freeze on the Editor when moved to a different screen

Reproducible with: 2020.2.0b3, 2020.3.1.1f1, 2021.1.1f1, 2021.2.0a11
Not reproducible with: 2018.4.33f1, 2019.4.23f1, 2020.2.0b2

Notes:
- The issue has been tested and reproduced on windows
- The Editor is also repainted when moved to a different screen

    Resolution Note (fix version 2022.1):

    When changing DPIs on Windows, we have to recalculate the window size and setup our our render surfaces again. This is an issue all apps have to handle in various ways.
