glTexImage2D much slower on Android 4.2.2 than 4.2.0

Question

We recently upgraded our Android devices from 4.2.0 to 4.2.2 only to realize that everything is now stuttering madly.

On Android 4.2.0 or lower, this call required roughly 15 ms.

glTexImage2D(GL_TEXTURE_2D, 0, GL_LUMINANCE, width, height, 0, GL_LUMINANCE, GL_UNSIGNED_BYTE, buffer.position(position));

On Android 4.2.2, the same call requires between 100 - 195 ms. What on earth has changed that would cause this? We are multiple developers testing across multiple devices and are all getting this. I can't see anything in the change logs that would affect this. I have no idea how to move forwards from here.

As a note, the buffer in the above call is a ByteBuffer returned from MediaCodec.
