There was an issue related to THREE.js — Im trying to figure out if this is something that should be brought up here, or with them. THREE.WebGLRenderer: highp not supported, using lowp instead.

The image is supposed to be of a Minecraft player. It can be seen in all other browsers that I have tested. I would guess that either Brave is supposed to have some sort of device support indicator, OR Three.js is failing to detect that it is executing within a chromium browser.
