Mouse pointer jump to parking position when change layer on QMK keyboards

[nguyenhaiac]

I'm using a keyboard with qmk firmware (vial-qmk fork).
Whenever I using a layer change key, they mouse pointer jump to the top right corner (parking position). Also this only happen in my Linux Machine.

Here is my setup:
Linux (A device) - Windows (B device).
When the pointer is in the Linux machine, when pressing layer change, pointer jump to parking position
When the pointer is in the Window Machine, pressing the layer change key doesn't affect mouse position.

Not sure how it could happen since theoretically the layer change key doesn't send anything to the host device.

Please let me know if I can provide any further information.

Can you usbhid-dump -e all with keyboard connected directly and then use the layer change key to record what's getting sent?

an update for this:

This issue actually happens on Windows as well, if I have only one Windows machine plugged to they deskhop, the pointer also moves to the parking position when pressing layer change.

I suspects that this happens in the primary machine (A device/only device)
