Trackpad zoom problem

Hi!
I’ve been playing around in Rh8 grasshopper and have found that after some panning and zooming around that the trackpad gesture of pinch in and pinch out will freeze and become unresponsive. After a minute or so, the gestures come back.
I’ve found the gesture disabling in the grasshopper canvas, then affecting the rhino viewport.
I am not sure if its a grasshopper issue or RH8 issue.

RH8 on M1 Max MBP.
