some map data have different show in different zoom level

some map data have different show in different zoom level . for example I draw some walls, and the adjacent walls will fill the grey face between them;


how to relsove this problem ? i need help

The issue names no files, tests, or reproducible dataset. Start by reproducing the wall example at multiple zoom levels and trace how the map data is converted into vector tiles. Done means the adjacent walls render consistently across the affected zoom levels.
