After investigations: If you increase layers count on OpenGL canvas, there is no issue. If you increase layers count on legacy canvas, add a trach or pcb text on a new inner layer, and then switch to OpenGL, there is a visibility issue (tested with demo "interf_u.kicad_pcb") > >> - Microvias layers are incorrect: currently, it is created from >> the top to the bottom layer.

When I encountered this "issue", the currently selected layer pair was Front+back, and the error message was "Only through vias can be placed between front and bottom layers". Therefore no bug. I don't know what is the best way in this case: - Show this message. - Place a through via. - Place a blind/buried via which is on all layers (which is what happens in legacy mode). > >> Remark: I like the way blind/buried vias are shown in GAL mode. >> Perhaps a similar way could be used for microvias ( which are in >> fact just blind/buried vias with a specific size) > > Good point, it should not be very hard to modify. > > Regards, Orson > -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
