[Nicholas Savenlid]

I can no longer draw arc in footprint editor.

never was a problem before.

the arc refuses to end-point at the point you indicate it woobles arround.

Can't confirm on Linux.

this video ilustrates how arc just "jumps" around

I cannot duplicate this. I just tested this using:

There have been a lot of changes recently with the opengl canvas so the
issue may already be resolve. Please try the latest nightly build to
confirm if this problem still exists. Thanks.

donwloaded latest possible.
Same problem

As you can see below some details differ from your installation.
I did not tick any boxes during install, no libs, no footprint, no help, and no environment variables.

maybe the lack of environment variables had some bad influence.
dont know
seems far-fetched tough.

I got another bug report about this issue. Because I am unable to reproduce the problem, I am looking for common traits in the reports that could help me pinpoint the problem.

@Nicholas @Novak
Have you built your binaries using msys2? If not, where did you get them?

[Nicholas Savenlid (nicholas-z)]

I downloaded nightly just from kicad download page, pre-built

x64 build
windows7

[Novak Tamas (novak-7)]

Me too: installed directly from "kicad-r7822.cf373e543-x86_64.exe" just downloaded.

[Novak Tamas (novak-7)]

Some more info for investigation:
- it shows the same problem with drawing arc when switched to Cairo canvas.

- I've installed the same version to another box with Windows 8.1/x64, different video (Intel G41 vs. Radeon HD5570) and also does the same both in OpenGL and Cairo.

[Novak Tamas (novak-7)]

- arcs already placed can be edited normally.
- after placing the center, then placing one end (and defining radius),
  very small mouse cursor up-down moves cause large jumps (~30 degrees) in arc's size.
It seems to be a proportinal ration problem from mouse moves to arc angle.
