Enabling NKRO via Fn+N on the K3 Max causes keys presses to be randomly duplicated even though no typos are made. The amount of duplications seems to correlate with typing speed.
This does not happen if the keyboard is connected via cable or if NKRO is disabled. The keyboard still correctly detects 20+ simultaneous key presses in 2.4GHz+NKRO despite this bug.
