That is by design -- it's a performance vs. accuracy tradeoff. Markers
are drawn only once and then stamped to the nearest pixel boundaries.
What you're seeing is the result of this rounding. And since each
marker is rounded in isolation, you don't see smooth stepping as a
classical line dra
The positioning of markers seems a bit off, especially when a line is
moved around with the pan and zoom tool. They don't follow the line they
are in, and seem to follow a much lower resolution line. Try the
following example, and use the pan and zoom tool to move the lines around.
