Robert, Transparency wasn't an issue (that was a missing GL_BLEND) but there are a couple other interesting things I discovered with texture arrays:
1) After loading a GIF, I had to manually call image->setInternalTextureFormat(GL_RGBA8), otherwise I get this message and a blank texture: Warning: Texture2DArray::applyTexImage2DArray_subload(..) given image do have wrong dimension or internal format. The original internal texture format was "4" which doesn't appear to be legal even for glTexImage; perhaps glTexStorage is being more strict. 2) When using the LINEAR_MIPMAP_LINEAR minfilter, along with calling tex->setResizeNonPowerOfTwoHint(false), the image appears black and I see this message: Warning: detected OpenGL error 'invalid operation' at StateSet::compileGLObejcts() compiling texture attribute Texture2DArray. Again, these may just be glTexStorage strictly enforcing things that glTexImage was lenient about.
