Vive Touchpad wrong value immediately after touching

Hey,

I’m using the touchpad of the Vive controllers for swipe motions (delta movement). I got everything working correctly, but lately there seems to be issues with the trackpad value immediately after touching.

Here are some snippets from MotionController(L)ThumbstickX node printed to the log, X Axis value of the left trackpad.
The controller was touched at only one position at a time.

The red values are wrong values that appear directly after touching. As you see the amount of wrong values differs as well. Sometimes there are up to 5 wrong values before the right value is appearing.

Anyone else who noticed this or anyone who knows what could cause this?
