Normal mouse scroll triggers limited to about two activations per second

Hello,

my normal mouse Scroll Up and Scroll Down triggers seem limited to roughly two activations per second. Even when I spin the wheel much faster, BetterTouchTool only executes the assigned action about once every half second.

This affects all scroll shortcuts, not only Keynote or one specific action.

I have already tested the following:

  • Scroll Wheel Repeat Delay is set to 0.0
  • High level mouse event recognition was tested both enabled and disabled
  • BetterTouchTool was restarted after changing the setting
  • Only one simple action was assigned
  • Different actions and applications were tested
  • No other mouse utility appears to be running
  • The same speed limit remains for every scroll trigger

My setup:

  • Mac: Mac mini, 2024
  • macOS: 26.4, build 25E246
  • Mouse: ROCCAT Kone Air
  • Connection: [Bluetooth
  • BetterTouchTool version: [6.663 (2026072309)]

Is there another debounce or rate limit setting that could cause this, or could this be a compatibility issue with the mouse?

Thank you.
