mouse jumps in dual screen

Windows 8, Fujitsu Q702 Stylistic hybrid, second monitor through HDMI port.

My mouse jumps about every 10 seconds to the seam between the two monitors (upper left corner).

It's not the mouse -- I switched it out. If I switch from "extend screen" to making the second screen primary, it jumps to the right side. That suggests to me that this is a configuration problem, not something physical. But I don't see anything to configure!

So very frustrated. :(
