Trying to use glMap/glUnmap (PBO) instead of glTexSubImage3D to update subrects in array texture's layer with new data. But after unmapping buffer and calling glTexSubImage3D with null "pixels" argument subrect of layer is always updated with black pixels. does i32f texture arrays could be streamed with PBO? or maybe i`m missing some simple things?

If you post more info, driver, os, hw and piece of code we can tell you more... Right now.. it can be your bug, or driver bug or hardware doesnt support feature.
