Inventing on Principle

It was definitely nVidia, and crashing with either Cg & HLSL, I don't have the code available anymore, but it might have been a similar issue to the DX9 one I linked above, ie. an error in the shader code that wasn't reported correctly.

It is weird since in 6 years working with shaders (both in FX Composer and directly) I've never had a video driver crash, let alone BSOD (I don't even know how it looks like now). Maybe I've been using a wrong operating system?

Seriously though, Cg, HLSL and GLSL are restrictive enough, there is little you can do to force the crash. Sure, there are ways to mess up with the API, but I don't think using badly written shaders is one of them.

Think again, just check the ANGLE issues tracker (f.i. http://code.google.com/p/angleprojec.../detail?id=198). You can also have a look at the detailed driver release notes from nVidia, AMD & Intel. And if Google takes the trouble of maintaining hardware and driver compatibility lists for Chrome, believe me, that's not for the fun of it either ;-)

Then you should have stated that buggy software that tries to use shaders among other things, can crash PC, not shaders themselves. The link you have provided redirects to ANGLE issue tracking support. The only thing you prove by this is that ANGLE has issues but you did not address any of my shader questions.

In any case, ANGLE is just an application of Adapter (or "wrapper" in some literature) software pattern. In no way it will help to resolve API issues as you are just redirecting OpenGL ES API, on top of which WebGL is based on, into Direct3D API. I think this will create more issues than it will solve.
