Line dash pattern symbol gets displaced along line when feature crosses canvas border

When setting a dash pattern symbol the pattern gets uncontrollable when feature crosses canvas border.
I suppose it gets rendered starting from a visible part of the feature.
Setting dash size in map units doesn't affect positioning.
Setting "Avoid artifacts when project is rendered as map tiles" doesn't help, though this is the expected behaviour.
So there is no precise control of what feature looks like, i.e. dashes move away from feature corners.
This video demonstrates the issue.

Quoting Nyall Dawson from https://issues.qgis.org/issues/16051:
This is caused by the automatic clipping of geometries to the canvas extent (+ a small buffer). You can prevent this by clicking the advanced button in the symbol properties window, and uncheck "clip features to canvas extent".
This issue can be closed.
