<pre>The draws are:
341 glDrawArrays(mode = GL_TRIANGLE_STRIP, first = 0, count = 18)
342 glUniformMatrix4fv(...)
343 glVertexAttribPointer(...)
344 glDrawElements(mode = GL_TRIANGLE_STRIP, count = 18, type =
GL_UNSIGNED_SHORT, indices = NULL)
Removing the glUniformMatrix4fv call between the two makes the hang disappear.
This corresponds to removing the CONSTANT_BUFFER packet between the two
3DPRIMITIVE packets...</pre>
