This has been a minor annoyance for me over the last year or so. I have 4 monitors. On the left one, whenever I have a browser maximized, a sliver of that box appears on the left side of my middle monitor. I'm running Windows 10 with an nVidia 1070 Windforce GPU. Left monitor is an HP S2031. Middle one is an LG 24M35H-B.
Any idea's on how to get rid of this?
