TypeError: Cannot read property 'precision' of null (Brave)

Getting this error using the Brave browser on Windows 10.

I'm using create-react-app and "three": "^0.100.0" with npm.

Sry, this is not a library but a browser issue. You should ask the support of Brave browser to fix this issue...

Seems like this is being already reported/discussed in the mentioned link:

Just in case someone else has issues with this on Brave (I was going to comment on reddit but the thread was archived).

I think this might be caused by the device recognition shield in Brave, since device information from WebGL can be used for fingerprinting. By changing the setting for "Device Recognition" in Shield settings to "Allow all device recognition attemps" or "Only block cross-site device recognition attemps" you should not get this error.

Thank you @AnotherHermit, this was huge for me

Hello, any advice to manage this issue without the need of asking the user to turn off a specific setting in Brave Shield?
We have a Three.js object on our landing page and it looks a little bit disgusting to didn't see it when the setting is turned on...

Does this occur when using a local HTTP server, or also on a remote HTTPS server?

Have you asked Brave devs?

i get this error when trying to use google maps. the ui is missing i think because of this (only map is shown)

Please, report these issues to the developers of Brave directly.
