Windows taskbar thumbnail preview not working with Minimize window

SDL version 2.0.3
Windows 10
On minimize Window with SDL Minimize window, I see the thumbnail preview with last rendered frame. However, if I run one monitor and observe the thumbnail preview on second I see video played in preview.
Can any one help what is issue?

How do you think it should work? What you describe is how windows works. I don’t think it has anything to do with SDL.
