Rats nest disappears


#1

I occasionally have the rats nest disappear completely. The button on the left still shows “hide rats nest” so Kicad apparently thinks it is still being shown. Repeatedly pushing the hide/show button has no effect, the rats nest remains invisible. The only way to get it back is to re-read the current netlist, and then it shows up again. Just to be sure, I upgraded to the latest test version, but it still happens.

I am not sure that I am doing anything different when this happens. I think it may occur after I have placed a track, and then right-click to end the tool. But it catches me by surprise, and after clicking away on the hide/show etc, I can’t always recall the last action!

Did you try the [Redraw the screen of the board (F3)] button yet, up there where the zoom buttons are?
I remember such a behavior myself after laying down tracks the ratsnest would vanish and I needed to hit that button I think to get it back.


#3

I finally got a chance to try it again- F3/Redraw does not bring back the rats nest. So far only reading the netlist works (I suppose closing and re-opening the project would work as well).


#4

Just had it happen to me doing a layout in BZR 6097 (not a recent version) while putting down tracks - moving a footprint (or attempting to) did bring the ratsnest back to visibility (zooming or redrawing did indeed not help - didn’t try re-reading the netlist).


#5

Yup, have the same issue sporadically. But too rare in order to reproduce. Redraw does not help. Only close and open brings back the ratsnest.


#6

Happening regularly with Win64 v4.0.2 and the default canvas. The ratsnet disappears pretty regularly. Moving a component will sometimes bring it back (iirc), but re-reading the netlist seems to be the only workaround.


#7

What about toggling to OpenGL and back?


#8

Bump.

This has been happening to me with latest version, switching to OpenGL & back fixed it. Is it being looked at?

Rats net lost bug have been there for a long time (pop up rate once/month or so). Yesterday I did start new project and with it that problem pops up several times in hour. I did use Win64 version 4.0.2 and upgraded it to the version 4.0.5. The problem remains.
