Issue description

Switching the root window's mode property between MODE_WINDOWED and MODE_(EXCLUSIVE)_FULLSCREEN, and then setting it to MODE_MINIMIZED can make the Windows taskbar preview of the window appear odd.

The window on the preview has two menu bars and is displayed with wrong scale/position of it's contents.
Additionally weird transparent window silhouettes appear with wrong size and positioning (including being on a wrong monitor in a double monitor setup)

The game's window is back to normal after manually changing it to windowed mode (clicking it on the taskbar).

Feel free to check out the reproduction video:

Steps to reproduce

0. Use the minimal reproduction project, or:
1. Create a new project (I used Compatibility renderer) with a visible node.
2. Attach the script and run the project:

extends TextureRect


@onready var tree = get_tree()
@onready var Root = tree.root


func _ready():

#	start with MODE_WINOWED -> MODE_FULSCREEN -> MODE_MINIMIZED check preview

#	without awaits the preview looks differently but still not the same as the window

	await tree.create_timer(1).timeout
	Root.mode = Root.MODE_FULLSCREEN # MODE_EXCLUSIVE_FULLSCREEN also works
	await tree.create_timer(1).timeout
	Root.mode = Root.MODE_MINIMIZED
	await tree.create_timer(1).timeout

3. Hover over the minimized icon of the game on the Windows task bar.

Sometimes the preview changes to this weird white background with the project's icon in the centre instead.
