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 
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:
