I do also see a line with dotted style.

Yes, this is normal. Quoting the Postscript language reference 

setlinewidth (which is called when using the PSTricks linewidth parameter):

A line width of 0 is acceptable, and is interpreted as the thinnest line 
that can be
rendered at device resolution—1 device pixel wide. However, some devices 
not reproduce 1-pixel lines, and on high-resolution devices, they are 
nearly invis-
ible. Since the results of rendering such “zero-width” lines are 
their use is not recommended.

To suppress the line you must use linestyle=none.
