Snapping to the wrong side

Describe the bug
I drag a window to the right side. It draws the image as though it will snap to the right side. It then jumps to the opposite side.

I have multiple monitors. This does not happen on the other to monitors, only the primary one. Used to work before the Mojave upgrade. I had to remove/re-enable the accessibility menu to get the tool to work at all. It now sort of works but with this weird behavior now.

Device information:

  • Type of Mac: Macbook pro
  • macOS version: Mojave
  • BetterTouchTool version: BetterSnapTool (latest as of 10/24/2018 in the app store)
