tkinter canvas create_arc method giving round edged arcs

[S. klein]

Hi,

please see this issue here:

I am drawing arcs in tkinter. They use the 'arc' method so only have an outer edge of a specified width and colour. Annoyingly some arcs seem to have randomly have a rounded edge. Does anyone know if this is a bug or if it can be fixed?

Another stack exchange user found that this occurred when the arc was 90 or 271 deg. long.

There also seems to be a glitch where decimal degrees cause much larger arcs to be drawn.

Thanks for any help,

S.
