Rendering & troubleshooting

The map won’t load or says “WebGL is not supported”

Article · 1 min readUpdated

Mappi draws the map with WebGL, your browser’s graphics engine. If you see “WebGL is not supported” or a blank preview, turn on hardware acceleration in your browser settings, update the browser, and reload. If it still fails, try another browser or device.

Step by step

  1. Turn on hardware acceleration

    In Chrome, open Settings and then System (in Edge, System and performance), turn on Use graphics acceleration when available, and relaunch the browser.

  2. Update your browser

    Install the latest version of Chrome, Edge, Firefox or Safari. Older versions can have graphics bugs that block WebGL.

  3. Reload or try another browser

    Reloading the page or relaunching the browser starts the editor over with an empty map, without a warning, so save your map first if you can. Then reload the editor, click Untitled map at the top and pick your map from the list. If the preview is still blank, open Mappi in a different browser or on another device to tell a browser problem apart from a device problem.

Other things that block the map

  • Some company or school computers turn graphics features off. Ask your IT team, or use a personal device.
  • Browser extensions that block scripts or canvas drawing can stop the map from rendering. Try a private window with extensions off.
  • Remote desktops and virtual machines often have no graphics acceleration.
