I’ve noticed this green trace pops up sometimes and I can’t get rig of it or figure out what it represents. On the picture that’s the bright green trace named GND.
I am not able to select it, and it remains there even when I deselect the visibility of all layers.
Is this a bug or is it representing something I don’t understand?
Is it still there in different canvas views and when you restart & reload PcbNew ?
Being unable to select suggests it is some display artifact, but even if you cannot select it you can guess at the co-ords of one end being = that Pin 16, so you should then be able to find it in the .Kicad_pcb file.
The pin is net tagged GND, so there is meant to be a GND connect, so the trace is valid.
The red partial trace heading at / 45’ seems more suss…
