How to Fix Google Chrome's WebGL Not Working

Often, people stumble upon an elusive bug that seems to lurk in the unchartered territories of Google Chrome's rendering capabilities: WebGL not working. No need to send up a distress flare! This blog is your trusty GPS through this virtual wilderness. We'll be delving into the complex world of Chrome's hardware-accelerated 3D graphics subsystem, known more colloquially as WebGL, to rectify this vexing issue.

Understanding WebGL & Its Importance

The mighty WebGL, an acronym for Web Graphics Library, is a JavaScript API that's used to render interactive 2D and 3D graphics within any compatible web browser, sans any plug-ins. From animated graphics, data visualizations, interactive gaming, to scientific simulations, WebGL is the unsung hero behind a smoothly running web application. But, what happens when this soft-spoken Goliath decides to take a nap?

Signs That WebGL Is Not Working

Now, here's a conundrum: How do you know if WebGL is causing trouble? Crux of the matter, in fact. If you're navigating a website rendered via WebGL and suddenly run into issues like chopped graphic displays, browser slowdowns or crashes - it's likely time to sound the WebGL alarm.

Kickstarting Your WebGL - Step by Step

With that background, here's the skinny. Below is an elucidative walkthrough, peppered with esoteric browser parlance, to have your WebGL back up and running.

Step 1: Enable Hardware Acceleration:

This is the first port of call if your WebGL is acting up. Navigate to Chrome's 'Settings' -> 'Advanced' -> 'System', and check if 'Use hardware acceleration when available' is turned on. If it's off, flip the switch.

Step 2: Adjust WebGL Flags:

Next, plunge into the labyrinthine world of Chrome's 'flags', essentially experimental features not yet ready for primetime. Type 'chrome://flags/' into the address bar and search for WebGL. The 'WebGL Draft Extensions' and 'Override software rendering list' flags could be the villains. If they are disabled, enable them.

Step 3: Update Chrome:

A stale version can sometimes be the offender. Please ensure you're running the latest Chrome version under 'Help' -> 'About Google Chrome'. Lucky number 7 - if you see that your version starts with 7, you're in the clear!

Step 4: Check with 'Chrome GPU':

Here, we are checking to see if WebGL is functioning as it should. Type 'chrome://gpu' in the address bar. Under 'Graphics Feature Status', if the status of WebGL reads 'Hardware accelerated', it's thumbs up!

Step 5: Consult WebGL Report:

If you're still plagued with issues, hone in on the problem by generating a WebGL report. Access '', which shows your browser's WebGL API capabilities and support. This can provide clues for further troubleshooting.


Today, we've navigated the winding paths of Google Chrome's WebGL issues and explored the labyrinth within. With pearls of wisdom like enabling hardware acceleration, adjusting WebGL flags, updating Chrome, and consulting WebGL reports, hopefully you're well-equipped to fix any WebGL related predicaments you might come face to face with.
