Turns out some drivers DO care. Specifically new hardware from a particular hardware partner. Original PR comment:

Simple missing case, should have implemented it in the first place. Also noticed that from a recent change to move to raw buffer writes, the debug output UAV offset was being set to a non-dword aligned offset. No drivers/hardware seem to care, but it's a concerning thing to leave as-is.

(cherry picked from commit 080aeb7)

Looks good to me. Good to see PIX getting a fix to keep shader debugging solid.
