Invalid tmux term causes irssi issues
Today I finally switched my long-running IRC screen session to tmux. I rarely disconnect so I was simply waiting for a “good” time. After a few minutes I noticed that my irssi scrollback was misbehaving; only half of my window would redraw when I pressed PgUp of PgDn. I had manually set TERM=xterm in my bashrc; however, tmux advises only using screen or screen-256color as the term. I have no idea why I had specified term within my bashrc; removing the line and restarting tmux corrected the issue....
