Sometimes steps over borders

In the y-direction it sometimes steps over borders like this very white image. Is there a way to set a threshold?

We discussed in #3 but we didn't come up with a satisfying solution on how to change the value UI-wise.

All-tough judging from your screenshot the error is a different one: it seems that the dimensions screenshot is not in sync with whats on screen. Dimensions takes a screenshot of the visible area whenever it gets activated and then again whenever the user scrolls. When the DOM is changed via Javascript, Dimensions doesn't take a new screenshot. Thats when it gets out of sync and you start to measure invisible dimensions.

Dimensions probably should listen to DOM changes. Any pointers on what DOM events there are?

add-on: I run into this problem myself very often. To fix it I either press Alt+D twice or scroll a little bit to restart dimensions.
