Black Canvas in some PC (Chrome Browser)

Hello,
I'm not sure if this was flagged already.
I'm developing a demo for our team and send it out for my colleagues to look at the demo. See Demo1.png

On two PC's running Windows 7 we are experiencing rendering issues. All PC's are running Chrome 56. We see a black screen with only a blinking part. See Demo2.png


If anyone had this issue, please let me know what could cause this and what can be done to resolve it. (Using another browser is not an option as it is very complicated to have something installed-IT wise and procedures)

Thanks

Hello
Could you tell us about PC, where this issue happens, in more details (model of GPU)?
And could you make a screenshot of this page

on these devices?

Thanks Roman for the fast response.

WebGL 2.0 is reporting video driver error. Could this be the cause? Video driver?

Hello

Video driver?

It seems so, but could you tell me the model of video card ?

Hello Roman,

Our PC's are very basic ones. They are equipped with on board GPU.
Video Adapter Intel(R) 4 Series Internal Chipset (3880752 KB)

Attached is the PC's report on Hardware.

Thanks

Hello
This cpu is rather old (2008) but we'll try to find this architecture and test your case. Thanks for the feedback
