Editor lags for a second when moved to another monitor with different scale and maximized

Window management

May 29, 2020

How to reproduce:
1. Create and open a new project
2. Move Editor window from one monitor to another and double click the title bar to maximize it

Expected result: no lag appears before maximizing the window
Actual result: Editor lags for a second before maximizing the window

Reproducible with: 2019.1.0a10, 2019.4.0f1, 2020.1.0b12, 2020.2.0a14
Not reproducible with: 2018.4.23f1, 2019.1.0a9

Note:
- only reproduces if one of the monitors has display scale set to more than 100% (as an example 125%) (For Windows operating system go to Settings > System > Display > Scale and layout and set "Change the size of text, apps, and other items" to 125% or higher)
- in lower specification devices Application.Reload loading window may appear
- tested and reproduces with Direct3D11, Vulkan and OpenGLCore graphics APIs

Resolution Note:

This behavior is required in order to refresh editor window resources. Scripts need to be reloaded to refresh new dpi resources.

I'm also getting this issue when moving a window from screens with different resolutions and not getting this issue with any other tool on Windows. (Unreal, lumberyard, modo, chrome, etc)
