far2l freezes when ran outside terminal window (FreeBSD)

[blackhaz]

Please help to troubleshoot this. When starting far2l from a terminal window, everything works fine (although I have a blank terminal window occupying desktop.) When starting far2l directly from, say, Xfce panel or Thunar, far2l never shows up, the whole X server freezes and I have to kill it and restart it. Is there anything I can do to fix this?

Running FreeBSD 13.1, Xfce 4.16, zsh.
