These are just stripped down version of rendercopy for each gen.

What I would guess would be the key to understanding the issue
at hand, would be to start from just empty batch and then add
one stage initialization at a time, until the bug disappears.

But as our bdw doesn't seem to hit the issue reliably, I went
into setting up everything (used rendercopy).
