Windows 10, Lenovo, Chrome Official Build, WebGL Error

[andrew...@verizon.com]

1. A concise explanation of the problem you're experiencing.

- my machine cannot run this demo as of 2/8/18 and we have an app built upon it
- I am seeking help configuring my machine to understand the gotchas
- This demo ran fine on 2/7/18 and before

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

- The demo site

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

- I would like to vet our custom app before releasing it to my customers that likely also have this laptop

4. The Cesium version you're using, your operating system and browser.

- Windows 10, Lenovo Thinkpad, Intel Graphics 520 card
- I am getting a WebGL error with Chrome Version 64.0.3282.167 (Official Build) (64-bit)
- With EI11 and Edge I do not get an error

Andrew, in Chrome, go to http://webglreport.com
That will give some clues as to the webgl support of your graphics processor and Chrome browser. Check the same website's report in Edge browser. You should be able to figure out what webgl extension is not supported in Chrome. Sometimes there's a Chrome flag that can be set to enable whatever webgl feature is unsupported in Chromes default configuration. Good luck!

Aha! you already tried that, right?

Post the psecific webgl error you get in Chrome, there are many variations of webgl errors

I feel the root of my problem is here:

Andrew-

You haven't provided enough info to the forum for others to help you. God helps those who help themselves. 2 of your 3 links did not work. I don't know what topics you are trying to link to.

The "stigviewer" link regarding disabling WebGL says, "Specifically, web pages cannot access the WebGL API", so if that's your problem, it is not a question for the CesiumDev forum. 

If you have disabled WebGL, you have disabled CesiumJS.

Good luck. I'll see if I can help someone else.

Looks like there was a followup posted in that thread, maybe you will have some luck with that one.

Thanks,

Gabby
