Research direction
Reproduce the issue in mapbox-gl-js 0.28.0 using a positive line-offset and line-round-limit set to 1, then compare the rendering with the expected artifact-free result. Trace the line rendering entry point for these properties and investigate the behavior across the different line-join settings. Done means the reported artifacts no longer appear under the stated conditions.
