Description Ilia Mirkin 2016-11-20 01:17:06 UTC 
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.2d_alpha

The test sticks some data in via glTexImage2D (into each level), then renders a gradient to a FB, and then runs glCopyTexSubImage to overwrite part of each level's data with the new data. It appears that the first 32 pixels of level0 are good, but the next 32, which have the partial copy over them, were improperly initialized. Like a load was missing?
