Windows Aero Peek only shows the title bar when minimizing

Using Delphi 10 Seattle on Windows 10 as well as Windows 10 Dark VCL Style. When the window is in normal condition, hovering over the taskbar icon displays the full window in thumbnail. However, if I hide my application, then when I hover over the taskbar icon, only the thumbnail is displayed. Also, if I hover over a thumbnail, a window preview also shows only the title, nothing more. If I put my window back into its natural state, everything will work just fine.

I am sure this is due to the specific VCL “Windows 10 Dark” style, because other VCL styles do not behave this way. In fact, without using VCL styles at all, the preview only shows the client area of ​​the form and does not display the title at all. But using this style, I only see the title.

It uses an empty form using only the "Windows 10 Dark" style, without code:

Empty form

When the window is in normal condition, Aero Peek shows a penalty:

Normal condition

And when it is in a summary state, it shows only the title bar:

Minimized condition

And when you hover over the thumbnail, only the title bar is also displayed:

Preview

As you can see, this completely defeats the goal of Aero Peek. Something seems to be pushing him back to the old window style of Windows 3.1.
