I'd like to ask - I'm updating half of the texture with OpenCL program and another half on CPU. But calling:
glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, width, (height - delta_height), GL_RGBA, GL_FLOAT, data_v);
Updates half of the texture (done by CPU) and ignores texture updated by OpenCL. Note that I make sure that OpenCL finishes before I do the TexSubImage call.
Any idea/hint (e.g. what I missed)?

It appears that the gentleman thought C++ was extremely difficult and he was overjoyed that the machine was absorbing it; he understood that good C++ is difficult but the best C++ is well-nigh unintelligible.
