Hello!

I noticed something in the schematic. See pictures.

What is the purpose of the light green lines? Looking at the whole schematic, half of them seem
to have that problem or feature and as it changes with the zoom ratio, I suspect it might be a bug,
and it must be recent because I never noticed.
Anyway if it’s a feature, I would like to turn it off. Is there a way to do that?
Thanks

Where’s Waldo?

i.e. = please point to what you are concerned about, I can’t see it.

You’ve been playing with the colours in “Preferences” and after that clicked the “Grid” button in the editor.

Hello again!

Sorry, the pictures I sent show strange on my Ubuntu PC, but not on MacOs.
See how it looks on my screen, for instance on the letf pins 1 … 9. All the wires look
highlighted, except the one on pin 7. Then if I increase slightly the zoom factor,
all but pins 3 and 9.

As for the context, I changed for a new PC, better CPU and lots of memory. That
might have something to do with a different graphic engine.

NB: if I take a screenshot, it looks the same as in Kicad, which makes sense.
But the image is perfectly normal when looking from my mac.

Update: it looks like it’s a screen problem. I changed to a similar screen (same 4k display,
but smaller) and this one doesn’t show the problem at all. The display itself works usually
fine but there are apparently issues. Not sure of the warranty, it might be too old to change it.
Thanks for the replies and sorry for the kicad-unrelated mess!
