  • Framework version: deck.gl@8.8
  • Browser: Chrome/Firefox

Research direction

Start with the linked deck.gl ArcLayer Google Maps example and trace the GoogleMapsOverlay rendering path for the deck.gl@8.8 setup. Reproduce the rough lines in Chrome or Firefox on Linux, then verify that lines and arcs in the GoogleMapsOverlay example are antialiased without regressing the other listed integration flavors.
