The 4890 has a RV790 GPU.

I've run the trace again and also see an error similar to the one Gert
mentioned:

1639 Message api issue 1: FBO incomplete: no attachments and default width or
height is 0 [-1].

There are also more errors reported around glDrawArrays as follows:

major api error 2: GL_INVALID_ENUM in
glGetIntegerV(pname=GL_TEXTURE_BINDING_CUBE_MAP_ARRAY)

warning: dumping of normalized attribute (vertexCoord) not yet supported
