The Logitech Performance MX mouse wireless transmitter is picking up interference from something in the monitor. I would test by plugging the additional extension dongle cable that came with the mouse into the back/rear USB port on the P2715Q. Then plug the wireless transmitter into the other end of that dongle cable and move it away from the P2715Q. There are many threads concerning this mouse and lag.
