Mouse cursor stuck

[turbanisch]

I'm using Karabiner-DriverKit-VirtualHIDDevice to power kanata (to remap keys on my keyboard). The setup works fine fine with the keyboard + mouse combo I have at home and with the keyboard at my office – however, once I connect to the mouse I have at my office and start moving it, the cursor gets stuck in the upper corners of the screen. It still moves between the left and right corners but is confined to the edge of the screen.
Do you have any trouble-shooting advice? Both keyboards and both mice are bluetooth Logitech devices. The one that is causing trouble is an M720 Triathlon.
