Live demos don't work on multiple browsers

[BrandtM]

Tested with Firefox 67.0.2 and Chrome 76.0.3809.12.
Firefox console prints out:
es6.promise.js:110 Unhandled promise rejection TypeError: "this.uniforms[e] is undefined"
And Chrome prints:
picogl.js:3928 Uncaught (in promise) TypeError: Cannot read property 'set' of undefined

Despite the different error messages both browsers deliver an identical page. It's completely black but the menu as well as the code editor are visible.

I think this should be resolved in the new version with sdf support. Closing for now.

Sorry if it's obnoxious to follow up so quickly, but I don't think the live demo build has been updated to reflect this fix (I still get this error).

retrace seems really cool and I'm excited to try it out! I've written a lot of SDFs in the past, never with tooling 1/10 as nice as this :)

@MaxBittker No, not at all, and thanks :) It's a bit hard for me to debug this though, as all scenes work perfectly for me on both my home & work mac os setups running the latest/almost latest versions of chrome & firefox.

Do you experience the same issue with all scenes? Could you provide some info on your environment? (os, browser, screen resolution, gpu & gpu driver details would be fantastic).

I recognise this error string, though. For me it usually has appeared after the webgl context has been lost at one point (i.e. webgl has crashed), in which case a browser restart fixes it for me. That'd be the first thing I'd try :)

Or, you're running Windows and are experiencing loooong shader compilation times (and probably other issues) due to ANGLE, which can cause context loss/a webgl crash. In which case there isn't much to do I think (you should still be able to run most demos with the sdf render mode, though).

linux, chrome, 2560 x 1440

the problem is the same in the scene links i tried from the readme, and persisted since I restarted my browser

I haven't tried cloning and building locally, maybe it's just that the new version hasn't been regenerated for gh-pages?
