A UGA-165 & Windows 10, when dragging icons i see a trail of images

Windows 10 software using a UGA-165 & VGA adaptor that came with the UGA-165. The origonal screen is ok if i use my mouse to drag icons around, but the new screen (which uses the UGA-165) leaves a trail of icon images, or partial images of it across the screen as i drag any icon around. Once i let go of the icon all copies disappear and the icon is on the screen just where i dropped it. I do NOT have “pointer tails” enabled and am using a wireless trac ball mouse. I dont see it as a bad issue, just odd. It almost seems like a refresh issue of some sort.
