BUG: Visor Activates on Trackpad Gesture

I’m having a problem where when I scroll up or down a web page using two fingers, about 20% of the time the gesture will trigger the TotalFinder Visor and bring it in front of the web page. Here are my touch settings (Wacom Intuous):

OS 10.10.2 / latest TotalFinder version.

Bug is still present in 1.6.27
