mouse drift when moving

[bc347]

When I move any direction, my view (or mouse?) drifts to the right and up. If I hold down the forward key, and hands off the mouse, after a few seconds, I am looking up at the sky. Pretty annoying to play because I'm constantly fighting the mouse to recenter my view.

The culprit seems to a Razer Tartarus Pro keypad. The problem goes away when I disconnect the keypad. The strange thing is only KF2 has this problem. Other games like BF2042, CoD Cold War and Vanguard, and Elden Ring do not have the problem. Probably the Razer Synapse software is not playing nicely with KF2.
