Rendering of WebGL does not correctly work in many pages. WebGL content appears either white (1), or very overexposed (2).

Example (1):
https://threejs.org/examples/#webgl_materials_lightmap

Example (2):
The header of https://acko.net/

I attached a screenshot showing (2) on M57 vs M58.

This happens both on my laptop and desktop (both on 10.12).
