    $\begingroup$ GL_SHADER_STORAGE_BARRIER_BIT Wrong barrier. The barrier you provide states how you will use the memory. Not how the shader wrote to it. You are doing a pixel transfer, so you need to use GL_TEXTURE_UPDATE_BARRIER_BIT $\endgroup$ Commented Nov 5, 2016 at 17:57

    $\begingroup$ Are you sure? According to the docs, GL_TEXTURE_UPDATE_BARRIER_BIT is used when synchronizing calls to glTexImage, and has nothing to do with the memory used in storage buffers. I think you meant GL_PIXEL_BUFFER_BARRIER_BIT? $\endgroup$ Commented Dec 9, 2016 at 4:00
