System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1650 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.11

Blender Version
Broken: version: 2.93.1, branch: master, commit date: 2021-06-22 05:57, hash: 1b8d33b18c

Short description of error
Issues when changing windows between monitors, minimizing/maximizing the main window

startup and userpref 2-91.7z

startup and userpref 2-93.7z

startup and userprefs.7z

Exact steps for others to reproduce the error
In 2.91, the windows act as expected:

Changing them between monitors moves the taskbar icon between them right away
Minimizing one does not minimize the other
Clicking on the main window does not bring the secondary window into focus, allowing for the use of other programs on the second monitor, for instance, a browser open with reference images.

In 2.93.1, the behaviour is not as expected:

Changing windows between monitors works, but the taskbar icons remain on the monitor they were previously on
Minimizing the main window also minimizes the secondary, maximizing the main window also maximizes the secondary window, but it comes back smaller on the screen. The opposite is not true, minimizing the secondary window only affects the secondary window.
Using the main window forces the secondary window back into focus if it is on the second monitor, not allowing for the use of other programs on the secondary monitor. The opposite is not true, the secondary window does not force the primary back into focus.
Fiddling with the taskbar icons (clicking on them repeatedly) eventually sends the window's taskbar icon to the appropriate monitor

The attached files include the start up file and userpref of both versions in which this has been tested.

It is by design I guess. Changes were made on window management for 2.93 release
(refer: https://wiki.blender.org/wiki/Reference/Release_Notes/2.93/User_Interface#Window_Management)

@Harley , can you take a look at the report? Not sure but possibly this behavior is intentional.

This is unfortunate in that case, this new management style is frustrating and counter productive. Is there any way to change this in the settings? If not, I think this should be added as a feature to the next release.

Perhaps this new system is better for single monitors with multiple windows, but it is quite terrible for multi window multi monitor.

It’s by design, but there is enough flexibility that you can probably get what you want.

The main blender window creates child windows that can each be individually minimized. But they are grouped together and will all minimize if you minimize the parent. This is convenient in many scenarios and was long requested by users who work with many windows at once since they no longer have to minimize each one to do something else.

But if you create a window with “window / new main window” you will create a new separate parent window that is not grouped, will not minimize when you minimize other main windows, and it can have its own children if you want. Basically it will behave exactly as you are used to. And you have can have any number of main windows, each with children, arranged any way you like.

This was a part of many changes to do with window creation on Windows, mostly to properly handle multiple windows on multiple monitors.

Well, that'll work well enough. Thank you for your time.

Closing as this is expected behavior.
