Selecting "Start to Block Scrolling" makes entire system hang.


Describe the bug
I actually wasn't looking to use the "Start to Block Scrolling" action, but rather selected it by mistake. It immediately made my entire system unresponsive. It took me about five minutes to be able to open up activity monitor and force quit BTT.

Important to note that I didn't even activate the trigger, I merely selected the action from the drop-down list and that was enough to lock everything up.

After restarting BTT the behavior persisted when I tried to select that action and change it to something else.


Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
The trigger was been configured under the Touch Bar section.


Device information:

  • Type of Mac: Macbook Pro 2021 16" M1 Max
  • macOS version: 13.4.1 (22F82)
  • BetterTouchTool version: 4.336

Additional information (e.g. crash logs, related issues, etc.):
No crash logs for produced after I force quit BTT.

I tried to reproduce, but it all seems to work fine here. Do you remember what kind of trigger it was that you assigned the action to?

I was configuring a "TouchBar Button" type trigger and this action was a subaction.
