Beta Renderer

Overview

The Google Maps JavaScript API team is developing a new renderer which will eventually replace the current renderer. A beta version is now available. Follow the instructions on this page to opt in for testing the beta version.

Read the source code or view this example full screen.

Features

• Animations on zoom and pan
• Better frame rate.
• Markers with {optimized:false} do not blink during zoom.
• Info windows do not blink during zoom.
• Polygons do not blink during zoom.
• OverlayViews can hook into the animation frame loop, and render at fractional-zoom levels.
• Improved support for touch gestures
• Tiles load during touch pan and zoom.
• Touch works properly on Internet Explorer and Edge browsers.
• When the map div is resized, the map center is fixed
• Full-screen button now works properly.
• There is no longer any need to trigger the resize event manually.

How to opt-in

To opt-in to the beta renderer, update the script tag that loads the API, adding the following parameter to the end of the URL:

&v=3.exp&use_slippy=true

Your script tag should now look similar to the following example:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&v=3.exp&use_slippy=true/>

Update the script tag in a test or internal app to test whether your app works as expected.

What to test

• Rendering
• Do the map, markers, overlays, etc. appear in the right place?
• Gestures
• Does the map behave smoothly when you pan/zoom, using either a mouse (on desktop), or touch (on mobile)?
• Do click, double-click, and tap (on mobile), on markers work as expected?
• If you have info windows, do the contents behave as expected?
• API
• If you have any interesting JavaScript code that interacts with the Maps API, does it still behave as expected?
• Other
• Did you find any other bugs?
