I'm experiencing a problem with the way QGIS Essen 2.14.12 draws a marker line symbol at the end of a polyline. It only occurs sometimes, and sometimes moving (even slightly) the mapping within the window will make the "orphan" symbol disappear, or make it reappear. Zooming in/out will also have the same seemingly random effect. I hope the attached image shows the problem - note the floating V at the top end of the brown line.

orphan v marker symbol at line end

The offending V is an inverted V symbol and offset by 8mm relative to the non-offset symbol (which plays nice and behaves itself) see settings below.

Despite searching, I've not found an answer to this issue.

The issue arises because the symbol is asked to be located 8 mm away from its supposed location.

To overcome this, you will want not to offset the symbol but rather the marker location along - but on - its line. You will need a style with 1 line and 2 marker lines, one of which having an offset along the line of 8mm. This ensures it will not go outside of the line.
