Browser warning: Unable to initialize WebGL. Your browser may not support it.

[guaraqe]

I just tested the first example in this repo and I get the warning in the title. Afterwards, the example works as expected, and the console logs appear as expected also. If I replace (\s -> alert s) with \s -> pure unit the error disappears, as expected.

I tested it with Chromium 62, and another WebKit-based browser. Any idea on a possible reason for it?

Thanks!
