9.6s, which is around what 26 macport is, twice as slow as 27, but
about 1/4 the time it took with previous versions of 28. It also
doesn't seem to slow down too much (12.8) when I go full width. It's
still usable, for sure.

No artifacts here as well, so I'd say this is a winner, at least for me.

Thank you for figuring something out.

Aaron
