My guess: Timing problem. dwm resizes st during startup, and then st
changes its window size, and either of the affected applications does
not update the window size when this happens.

I would run mutt or vifm under strace to see if they get a SIGWINCH, and
if they react to it by re-reading the window size. If not, they may have
a problem if SIGWINCH occurs too early (they ought to register the
SIGWINCH handler first and read the window size second, not the other
way around).
