I am running node-js v0.11.11 and node-webkit v0.9.2 in Windows.

When I run nw webgl, a windows pop up, but the content is not rendered correctly. Here is the FULL screen shot of the window created by node-webkit:

Same problem here, also on Ubuntu 14.04.

It might be related to an issue with webkit and our hardware/drivers. @petre2dor and @fyears, what does chrome://gpu/ output?

There are also some related issues on node-webkit (such as this)...

I am running node-js v0.11.11 and node-webkit v0.9.2 in Windows. According to https://github.com/rogerwang/node-webkit/wiki/Extract-info-about-gpu , the extracted chrome://gpu info is here:

In order to enable Webgl in chromium I had to do this http://askubuntu.com/questions/299345/how-to-enable-webgl-in-chrome-on-ubuntu/299346#299346 Can I do something similar for webkit?

rc1 commented 10 years ago

Having the same problem here. I am running with (in package.json): 

"chromium-args": "--enable-webgl --ignore-gpu-blacklist"

Using with the nouveau drivers and a NVIDIA GeForce GT 720. With the above arguments in Chrome WebGL appears to be working.

Some questions I be greatful if anyone on this issue could answer:

  1. Did it work before upgrading to 14.04?
  2. Are you on the OS driver too or native NVidia drives? Does this make a difference?

Hoping to try two myself soon.

please excuse the --disable-javascript that was to check the args were being applied
