Describe the bug
When BetterTouchTool’s “Show HUD” action is triggered, the scroll input that triggered it does not get passed through to macOS. As a result, the intended system scroll (e.g. scrolling a page/list) is blocked/consumed whenever the HUD shows.

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

Device information:

  • Type of Mac: MacBook Pro
  • macOS version: macOS Tahoe 26.2
  • BetterTouchTool version: Version: 6.111 (2026012703)

Additional information (e.g. crash logs, related issues, etc.):

  1. No crash, just input handling behavior.
  2. Steps to reproduce:

    1. Configure a gesture/trigger that uses “Show HUD” (e.g. a scroll gesture or a gesture performed while scrolling).

    2. Open any app with a scrollable view (Safari, Finder, Settings, Notes, etc.).

    3. Perform the scroll/gesture that triggers the HUD while attempting to scroll content.

    4. Expected: HUD appears and the scroll event still scrolls the content (passes through to macOS/app).

    5. Actual: HUD appears, but the scroll does not reach the system/app (scrolling is blocked/consumed).
