scroll event not smooth compared to native

Before bug reporting, please make sure you have tried the latest (alpha) version of BetterTouchTool and that you have already tried to restart your system :-). If you encounter a crash, please attach a crash log from the macOS from the "User Diagnostic Reports" section.

Describe the bug
I'd like to have an accelerated scroll on holding a side mouse button
I set an advanced trigger (in this testing example it's right mouse click)

exported_triggers.bttpreset (2.1 KB)

But then the scrolling is janky unlike the native "infinite scroll" wheel. Tried various settings for repeat rate, but couldn't get to the same thing

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):

Logitech Anywhere MX bluetooth mouse

modified janky scroll

native smooth scroll

Device information:

  • Type of Mac: MacBook Pro
  • macOS version: 13.4.1 (22F82)
  • BetterTouchTool version: 4.171

Additional information (e.g. crash logs, related issues, etc.):
LinearMouse app (disabled for this testing) does it wonderfully, but it only works with key modifiers, so maybe you could copy how they do it?
