I know very little about this, but here's what I know: this feature
relies upon the "ti" and "te" terminal capabilities. We use these
capabilities in tty_set_terminal_modes and tty_reset_terminal_modes,
respectively. In both cases, we output the terminal command only if
the tty->output FILE stream is non-NULL. So perhaps some timing
issues cause tty->output to become NULL before we get to
tty_reset_terminal_modes, or maybe it is still NULL when we get to
tty_set_terminal_modes? In any case, adding some logs to those places
could show if that is the problem.
Alternatively, could it be a problem with the terminal emulators, not
in Emacs?
