Usually this black window (rectangle) appears at the same place as the
minimized window. When the app window is maximized again, it covers the black
window. After several minimize/unminimize attempts, though, the black rectangle
will appear elsewhere on the screen. After that the main window unminimizes at
this new place, with its window controls (close box, minimize box, etc.)
unresponsive to mouse clicks.

SimHub (https://www.simhubdash.com) is a WPF app and requires .NET 4.8 to
function properly.
