No, I’m still on Mojave.

Anyway, one last thing to try. I was reading up on how MacVim handled
this same issue, and while their drawing techniques are quite
different, they did find performance problems with CGLayers so
switched to using CGImages. I’ve given that a go and I don’t think
this patch is quite as fast here as the CGLayer one, but it may be
faster for you.
