I run a fairly vanilla Emacs and it looked ok to me, but if I full maximised it on my retina mac it was visibly slower at things like scrolling than the current master branch. --000000000000e3b5dc05972732c2 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable

morning, and it seems ok.
