[bug] press caps_lock to change speed_multiplier leading to a reverse direction

[eret9616]

macos:Version 15.1 (24B83)
karabiner-elements:15.3.0

Press the Caps Lock key to change the speed multiplier, leading to a reverse direction.

I used to use the configs above,

I use the command + wsad to move the cursor, and when holding caps_lock, increase the move speed, when holding shift, decrease the move speed

it worked pretty well,

until after some upgrades (I don't know if it is a macOS upgrade or a Karabiner upgrade),

when I press caps_lock now, the cursor will move to the reverse direction.

Thank you for feedback!

This issue occurs because the values are overflowing. I've fixed the overflow issue in the latest beta version.

However, the root cause is that the values being provided to mouse_key are too large, so please specify values in the range of -1000 to 1000. If you feel the speed is insufficient, try adjusting the tracking speed in the Mouse settings under macOS System Preferences.
