When I use the grease pencil, I get broken, jagged / pixellated lines that should be smooth.

screenshot attached

See the "chinks" / breaks in the black line above.

When I zoom in, (here on the bottom left) the pixellation smooths out, though it doesn't disappear:

I'm using the latest build of Blender (2.78, 2016-09-15), and the strokes are made with the "Basic Brush".

Would appreciate feedback bout what's going on and how to fix it - thanks.

I believe your problem is related to a GPU / Driver issue. I am seeing the same thing you are seeing on a Mac with an ATI graphics card. If I save my blend file and open it on a different Mac with an Nvidia graphics card the lines are no longer jagged / pixelated. Check out this link for more information: Weird artifacts with Grease Pencil V2

I have not yet found a work-around for this problem, other than to render the final image/sequence on a computer with an Nvidia card.
