--- Comment #14 from Don McCurdy <dm at donmccurdy.com> ---
Here's a small, reproducible example:

- Demo: https://fp64-arithmetic.donmccurdy.com/
- Code: https://github.com/donmccurdy/fp64-arithmetic

An additional finding, for which I've added a GUI dropdown in the example, is that using GLSL 1.0 gives much more accurate results than GLSL 3.0 in Chromium-based browsers, unless the selected backend is Metal. In Safari, there are significant precision issues regardless of the GLSL version.
