BTT crashes after using a three fingers swipe on touch bar

Describe the bug
The application crashes sometimes when I'm using three fingers swipes with the touch bar.
Works well with 2 fingers swipes.

Touch Bar

The three fingers swipes are mapped to brightness control

This happens every single time to me too. It's really frustrating.

Happens to me too. Bump.

Unfortunately I think this can only be fixed by Apple. It only seems to affect some Macbook models.

You can try to enable the "Global" option for the gesture, then BTT will use a custom way to recognize the gestures, which however might not be as responsive.

I'm unfortunately seeing the same bug but only started appearing in 10.15.5, worked perfectly fine before then. Is the issue with specific models you describe just with this new update or has it been around longer?

Can confirm this bug. Happens with other configurations such as two and four finger. Quite unfortunate that these gestures don't work :frowning:

Possibly try the latest alpha I uploaded earlier today. It doesn't fix the bug itself (only Apple can), but hopefully BTT won't crash anymore.

I can confirm this bug too, with 2, 3 and 4 fingers swipe. Latest alpha version available in alpha channel is 3.358, April 16 2020 :slightly_frowning_face:
