There should be no circles around the colorbar.

See code here: http://nbviewer.ipython.org/6234558

Confirmed in a more recent version as well.

The issue is that for reasons that are not clear to me, the outline box of the color bar is drawn with a Line2D object ( https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/colorbar.py#L418 ) which should respect the rcparam set here.

I suspect the fix will be to change the outline to be a rectangle patch.

@eyurtsev as a side comment, can you paste the relevant code into the issue text in the future?

It will have to be a polygon, not a rectangle; it's not always rectangular.
