Wires with 'shadows'?

[eberaud]

Just curious, anyone knows why there are sometimes those shadows around the wires? They seem to disappear when I make a modification to the code, and then reappear after I run the VI.

they're called hash marks and indicate where LabVIEW compiler will optimize and fold it into constant code.

you hide these by changing your LabVIEW settings in the 'block diagram' page
