ArcGIS Basic 10.2 - Dash line symbol not drawing properly?

Hi,

I have multi-layered dash line symbol not drawing properly, as shown attached.

To me, it seems like ArcMap is not able to draw nice dashed line when there is too many vertex in the feature (as you can see with the green squares in the screenshots). The same happens with dotted lines.

Is there any way to improve that? I mean getting decent dashed lines?

For the time being, it is not acceptable.

Thanks
