Unexpected behaviour with Pcbnew manual routing

[Bogdan Șerban]

Manual routing sometimes gives weird results. I have attached examples below to better explain it, but the idea is that I get weird track shapes when I clearly shouldn't. I would expect the track to follow my mouse movements without me having to add unnecessary points, and without adding those 90 degree angles.
I'm not sure exactly what version introduced this behaviour, but I suspect this has been introduced in 5.1, it wasn't like this before.

This was the original forum thread: https://forum.kicad.info/t/why-did-routing-become-so-annoying/19493

As I said there, I would expect KiCad to offer two 45 degree corners instead of 90 + 45 degrees by default when it can choose between those.

Thank you for the report. Please add the files as attachments to the bug report. I am unable to view imgr links.

I attached the imgur images to the bug report and reopened the bug report

I suspect that this is resolved in master.

If it is not, please attach the board file that exhibits the behavior and a screen shot of your Interactive Router settings.
