It seems that Color attribute does not supplied in Draw
// Use vertices data.
location, ok := r.findAttribLocation(ns, "Vertex")
if ok {
gl.BindBuffer(gl.ARRAY_BUFFER, native.vertices)
gl.EnableVertexAttribArray(location)
defer gl.DisableVertexAttribArray(location)
gl.VertexAttribPointer(location, 3, gl.FLOAT, false, 0, nil)
}

location, ok = r.findAttribLocation(ns, "Color")
if ok {
    gl.BindBuffer(gl.ARRAY_BUFFER, native.colors)
    gl.EnableVertexAttribArray(location)
    defer gl.DisableVertexAttribArray(location)
    gl.VertexAttribPointer(location, 4, gl.FLOAT, false, 0, nil)
}

I added Color attribute binding, and it's ok now. I am not sure if I get the wrong code.

Apologies for the late response on this. Thank you for the detailed report @lazytiger -- I'll have to investigate later and see if this is still an issue in gfx.v2 and the gfxv2 branch of the examples.

I'm experiencing the same issue, but applying the fix did not help. No triangles, only the cleared color rectangles. All other examples run fine.

@awishformore @lazytiger can either of you confirm this is still an issue? for record, azul3d_triangles should look basically like this:

On OS X, the background bars will look smaller on a Retina display.

What are you seeing, can you provide a screenshot?
