I’m having troubles in trying to load the simple helloworld demo:
On a clean OS X installation with the latest chrome browser installed (MacBook Pro 15 late 2011)
In Crhome, to be able to have WebGL running, which seems to be off by default, I had to enable the flag:
WebGL 2.0 Mac, Windows, Linux, Chrome OS, Android
Allow web applications to access WebGL 2.0. #enable-es3-apis
And then I also had to:
Override software rendering list Mac, Windows, Linux, Chrome OS, Android
Overrides the built-in software rendering list and enables GPU-acceleration on unsupported system configurations. #ignore-gpu-blacklist
However … now the demo page load (no webgl errors) but it gives me a blank background instead of the cesium globe
No logs in the JS console. while this is what I have for chrome://gpu/ 
On the same laptop,
I tried also with Safari, Opera and Firefox.
on Opera I got the same white screen as with Chrome
while with Safari and Firefox I had no problems in loading the demo … have you any clue on what is wrong? It seems to me something related to the chromium framework (which opera and chrome are based on) In the past with the same laptop I had no problem with chrome and cesium. Is this introduced by a recent Cesium release ?
Thanks fr any advice,
