Browser hardware acceleration issue

Hi everyone,
I created my project with Three js and on some pc it doesn’t work returning black screen (on all browsers) but if I disable hardware acceleration from the browser (eg google chrome) the rendering starts working even if very slow.

While with hardware acceleration enabledit stops working and returns this message:
Uncaught TypeError: Failed to execute ‘shaderSource’ on ‘WebGL2RenderingContext’: parameter 1 is not of type ‘WebGLShader’.

You can help me?

many thanks

Ensure to use the latest OS, GPU driver and browser version and try again.

Hi Mugen87,
it’s the first solution I tried but without success.
The PCs that have this problem are some new and some old but all the software package is up to date :frowning:

Does it happen with other WebGL libraries or plain WebGL demos, too?

In general, I doubt this issue is three.js related. You probably want to execute the WebGL performance test suite to see how many breakage occurs on those devices:
