keyboard movement drift

Playing on Razer BlackWidow Ultimate keyboard with mouse.  Only in BF6 do I get a drift with movement after releasing a key (WASD keys).  It happens while walking and sprinting, though worse when sprinting.

I have no other devices (e.g., no controller) connected.  Just to be sure, I also disabled Bluetooth, but no change there.

(the only other similar bug report seemed related to a joystick setting, so it does not appear relevant to my issue)
