Description

I found that there are significant jagged edges at the seams of each tile.The wider the line setting, the more severe the jagged edges at the line junctions.

Research direction

The report names no source files, tests, or entry points and provides only a screenshot of jagged tile seams. First reproduce the issue with wider line settings in mapbox-gl-js, then trace the line-rendering path and determine how the tile junctions are handled. Done means the seams no longer appear and a regression test covers the affected case.
