We shouldn’t need the _APPLE calls anymore; VAOs take the OES extension path for WebGL 1, whereas WebGL 2 is now backed by GL 4 or ES 3 which both natively support vertex arrays.

Could you expand on this comment a bit? It's also a bit confusing, because you're talking about WebGL but inside a block that is doing desktop OpenGL. Maybe you could say something like "OpenGL 3.3+ removed the concept of default VAO. For that reason we need to explicitly bind to nothing before trying to initialise it." Or something :) > Source/WebCore/html/canvas/WebGL2RenderingContext.cpp:1070 > +#if !USE(OPENGL_ES) Swap this to be #if USE(OPENGL_ES) > Source/WebCore/html/canvas/WebGLRenderingContextBase.cpp:1780 > + if (buffer->isDeleted() || !deleteObject(buffer)) What causes this change?

Where is the WebGLBuffer getting deleted? For this, WebGL 1 spec states that most redundant delete functions (e.g. binding two VAOs to a single buffer, then binding the first VAO and calling deleteBuffer; binding the second VAO and calling deleteBuffer should do nothing) should be no-ops. Since we weren't preventing this, the conformance test was failing. I actually have a more general change that should affect deleteProgram, deleteShader, deleteTexture, deleteRenderBuffer, and deleteFrameBuffer as well as per the spec. Going to throw another patch at EWS, this time with the new test passes in /glsl3 and fixing the crash in deleteBufferBadArgs.
