With an open window on the desktop, and the mouse pointer hovering over the Taskbar Icon of the open window, the Icons image cycles back and forth for the time that the Icons window is open.

Here is a short video of what's happening. As I said before, this is new only in this latest Windows Insider version. It dropped on Saturday Oct 24th.

This short 27 secs video is shared from my OneDrive.
