pdf.js can't render fonts from v0.13.0-alpha4 to v0.13.0-alpha5 and above

[neves]

Sample package.json

{
  "name": "pdfjs",
  "main": "https://mozilla.github.io/pdf.js/web/viewer.html"
}

Same problem was reported here:
rhysd/NyaoVim#3

Console logs the follow error message:
[60314:1295:0323/104513:ERROR:gles2_cmd_decoder.cc(6874)] [.Offscreen-MainThread-0x7fe8cad97ca0]GL ERROR :GL_INVALID_OPERATION : glUseProgram: program not linked

OSX 10.11.3

Works till this version: (chromium 45.x)
http://dl.nwjs.io/v0.13.0-alpha4/nwjs-sdk-v0.13.0-alpha4-osx-x64.zip

Stop working here, till v0.13.0 final release: (chromium >= 46.x)

@ghostoy I can't reproduce this on my Mac, can you?

[ghostoy]

Not able to reproduce.

[rogerwang]

@neves what's your hardware configuration including GPU model?

[neves]

@rogerwang
MacBook Air (13-inch, Mid 2011)
1,7 GHz Intel Core i5
Intel HD Graphics 3000 384 MB
Is there anything I can help you with?

[neves]

Problem persists on v0.13.2 😭

[rogerwang]

it looks like related to hardware, we'll find a OSX with Intel gfx card to reproduce it.

[rogerwang]

@neves could you check the url with Chrome 49 in the same system then post the results of the page 'chrome://gpu' and the command line arguments of the Chrome process (ps aux | grep -i chrome); And do the same again for NW. Thanks.

[neves]

The only difference I spotted was NWJS has --no-sandbox

NWJS 0.13.2 (left) vs Chrome 49 (no difference)

Chrome GPU

NWJS GPU

[rogerwang]

Can't reproduce this on a MBP with Intel HD 4000 ...
NW should be the same with Chromium on this. We should find what's the difference with Chromium.

[ghostoy]

@neves Did you check if the PDF works with Chromium 49 on your platform?

[neves]

Working fine with chromium

[rogerwang]

Does 0.14 RC version work for you?

[neves]

@rogerwang 0.14 works!
I see it's using Chrome 50, could that be it?

[rogerwang]

It should be the reason.
