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