@Rovertek: yes, I think it’d still be useful for us. Send in a project that exhibits this issue on your Mac. Include any themes and plugins you’re using - that way we can test it out with the exact versions you’re using.
Try the same thing too with the built-in Styled Text or Markdown plugins. Are they really slow as well? If so, that points to something we could definitely look into further. (I appreciate that they’re not as complex as some third party plugins, but it helps us figure out what’s going on)
If you can provide a video (using Quicktime or similar) showing it being slow too, that’d be really useful.
