Incorrect behavior while routing and using switch track posture

[Art]

Switch track posture seems to be glitchy. Sometimes you have to route from the opposite end of the net to be able to run a track properly. Below I attached a sequence of pictures that illustrate the root of the problem.

On the first picture I started from a pad and ran a track without flipping it with "/" key. It behaves just like you expect it to.
Next I start a track from the same pad as before and in the same posture. I press "/" to switch the posture of track from the pad. The track flips. So far so good. I see the next (third) segment showing the way it supposed to be - at 45 deg angle. Next I click the mouse to attach the segment of the track and attempt to drag the next segment. The 45 deg segment disappears and track continues at the right angle to the second segment (counting from the pad). From there on you can route only at 90 deg angle and one step behind (in other words it is showing like it is going to route next segment at 45 deg but snaps back to the previous point of the track and routes from there at 90 deg.)

Oh yeah, I'm running PcbNew build after 2015-mar-04 on Windows 7

Can you reproduce on kicad-product-r5691.ba37f33? 30rd of May 2015.

Yes, the bug can still be reproduced on kicad-product-r5691.ba37f33

Can you reproduce this bug with the push and shove router? This is the one used on the GAL canvas (the OpenGL or Cairo view), which is supposed to replace the legacy canvas.

I was not able to reproduce that behavior in OpenGL or Cairo view.

As the issue is only with legacy i am tempted to mark this as wontfix as legacy canvas will soon be under gal
