ST (Suckless Terminal) sounds cool, but when I decided to give it a try it turned out that when combined with tmux, it is noticeably slower. Switching windows in tmux, whish is instantaneous in urxvt, visibly lags in st.
The workaround I've found at the moment is changing the value of the `termname` variable in config.h from "st-256color" to "xterm-256color".
Pretending to be xterm seems to pay off. So much for getting rid of xterm legacy!
