How are you doing this? Are you using some viewer? Or do you mean that you cannot display the 2d image in your browser?
It could be your GPU having some issues, so I would suggest updating drivers. I am also sometimes getting black flashing squares in Firefox, and it sometimes helps to minimize the browser window, and then restore it again.
Well, if anyone can test my html page in Google Chrome…I think that this will leave clear if it’s a local problem or a general problem.
I suppose that this must be a local problem (due to some wrong setting which I still haven’t found) but please, I encourage you to make this simple test please.
Possibly your client´s problems (or yours) are WebGL related, they may have some graphics card/browser combo which doesn´t support it. You may point them to
For me it works fine in Firefox, but not Chrome.
I have no experience in this, but in Chrome I could find the following after inspecting the element:
[.Offscreen-For-WebGL-0000000003F7F4E0]RENDER WARNING: there is no texture bound to the unit 0
