How to get rid of the white line in bottom when autohide taskbar?

I turned the option on of autohide taskbar. but after autohiding there's still a white line at the bottom where taskbar was. This annoys me and ruins the experience of full screen. how to fix it?

 

White line flashes at the bottom of taskbar when auto unhidden.


I'm running windows 10 Pro x86-64 Anniversary Update. I think my problem started with the cumulative update last week.

Make sure you autohide your taskbar in it's Properties. The best way to see my problem is to maximize a window and move your pointer to where your taskbar will popup or for that matter to hide it again. I get a white flashing line at the bottom of the taskbar when the taskbar un-hides or hides. It might take a few tries to see it. If I don't maximize the window, and the bottom of the windows isn't over where the taskbar come up, I get no white line.

Anyone else see this happening especially with AU and the latest cumulative update?
