I suspect #5178 to be the cause of this issue (this line), it should be:

var axisWidth = helpers.valueAtIndexOrDefault(me.options.gridLines.lineWidth, ???); // ??? maybe 0?

@jhaenchen what do you think?

@karolyi as a workaround and if you use the same width for all lines, your fiddle works with lineWidth: 1
