I was under the assumption that blorp behaved like meta in that it always created an image from the tile nearest to the copy region of the src/dst image - that is not the case. Sorry for not simply asking. This seems like a much better way to copy images. This series currently causes 6 crucbile tests to fail in <a href="http://func.miptree.r8g8b8a8-unorm.as">func.miptree.r8g8b8a8-unorm.as</a>pect-color.view-3d. Does your local copy fix these? If so, could you send it out? </blockquote><div> </div></div></div><div>Drp... I didn't run crucible. No CTS failures but I'm seeing the same 6 crucible fails that you are.

The R8G8B8A8 failures were do to sanitizing coordinates with the type from the wrong image. I also found a couple of other bugs. </div><div>There are still failures on 3-D stencil in those tests.
