But, currently, the ability to turn WebGL on/off is not included in the standard Settings interface of Google Chrome. Therefore, most Google Chrome users are clueless on how to enable or disable WebGL on their browser. Fortunately, there is an option under the ‘Experiments’ interface of the Chrome browser that allows you to do that.
Step-1: Open Google Chrome browser.
Step-2: Type ‘chrome://flags/‘ in the URL field and hit ‘Enter‘. This step leads to ‘Experiments’.
Step-3: Navigate down the list of ‘Experiments‘ and find out the ‘Experiment’ with the title ‘Disable WebGL‘.
(Note: When this option is enabled, the web applications cannot access the WebGL API. On the other hand, the web applications have full access to the WebGL API when this option is disabled. If the option is enabled, you have to disable it if you want to turn on WebGL.
If it is already disabled, then WebGL is already turned on.
Whenever Google Chrome starts up, the WebGL will be enabled, and the web applications can now successfully access the WebGL API.
In 2017, Google included WebGL 2.0 support to the Chrome browser in version 56. Moreover, it has provided an option to disable WebGL in flags. Recently, the Chromium team has discarded the WebGL 2.0 flag (#enable-es3-apis) from Chrome 63.
Use Ctrl+F to find the webGL2.0 setting and set it to ‘Disabled’.
