Browser settings

Hardware acceleration

You must enable hardware acceleration to use Confluence whiteboards.

To support the rendering of many elements on whiteboards, the whiteboard application uses hardware acceleration to use high-performance rendering capabilities inside modern browsers.

To enable hardware acceleration:

For Chrome

These instructions are for Chrome version 121.0.6167.85. See Chrome support documentation for more information.

1. Launch Chrome

2. Navigate to the Settings page (select the three dots icon in the top-right corner of your browser)

3. Select the System tab

4. Toggle ‘Use hardware acceleration when available’ on

For Firefox

These instructions are for Firefox version 122. See Firefox support documentation for more information.

1. Launch Firefox

2. Navigate to the Settings page (select the three lines icon in the top-right corner of your browser)

3. In the General tab, scroll to the Performance section

4. Uncheck ‘Use recommended performance settings’

5. Check ‘Use hardware acceleration when available’

For Microsoft Edge

These instructions are for Microsoft Edge version 121.0.2277.98. See Microsoft Edge support documentation for more information.

1. Launch Microsoft Edge

2. Navigate to the Settings page (select the three dots icon in the top-right corner of your browser)

3. Select the System and Performance tab

4. Toggle ‘Use hardware acceleration when available’ on

WebGL

You must have WebGL installed and enabled to use Confluence whiteboards.

WebGL is a capability available in all modern browsers which enables high-performance rendering.

To check if your browser supports WebGL - follow this link and the steps provided.

For Chrome & Microsoft Edge

Chrome & Microsoft Edge browsers fully support WebGL.

Ensure your browser is updated to the most recent version & ensure hardware acceleration is enabled to prevent any issues.

For Firefox

1. Navigate to about:config

2. Search for webgl.force-enabled and toggle this preference to true

3. Search for webgl.disabled and toggle this preference to false

4. Restart your Firefox browser to apply these new settings

Troubleshooting issues

Error screens

• If you see the “Update your display driver” error, hardware acceleration will likely be disabled. To fix this, follow the steps above.

• If you consistently see “Looks like you’re offline. We’ll sync any offline changes when you’re back.” You may need to contact your IT team to ensure http://canvas-workers.atlassian.com/ is on your allowlist and that web-sockets protocols are allowed.

Slow performance

• If your application is slow - it is likely WebGL is not enabled & installed or hardware acceleration has been turned off.
