--- Comment #6 from Nicholas Kazlauskas <nicholas.kazlauskas at amd.com> ---
I suspect that Alex is right about this being similar to the cursor update
issue - a large volume of color management changes through the full atomic
commit codepath would likely be quite slow. The dc=1 to dc=0 comparison is good
evidence supporting it as well.

Expanding the cursor path into a generalized plane update fast path would
likely resolve the issue, but may be tricky to do right.
