Last week I bought a 2018 13inch MacBook Air with Retina display running Mojave 10.14.1. I do lots of work on the terminal and have been disappointed to find that the terminal lags severely whenever color is used on the display. Whether I'm working in vim or on the command line, if color text is used, lag occurs.

I suspect it is a problem with my terminal settings, but I've tried everything I can think of to adjust these to optimize performance. Even a few colored characters on the screen decrease performance dramatically. Its worth noting that this does not cause a spike in CPU usage.

Any ideas as to how to fix this?

Note: I use the Pro profile with 100% opacity black background and 0% blur.
