} Adding a "sleep x" (x >= 0) to ~/.zshrc does indeed help.

Ahh, with that bit of data everything else makes a lot more sense.

Unfortunately I'm not entirely sure what to do about it.  In order for
the the ZLE_CMD_RESET_PROMPT change to have made a difference to the
behavior, the SIGWINCH must be arriving after zleread() is called for
the first time, because that's where zleactive gets set to 1, but it
isn't possible to tell exactly where in zleread() that happens.

Try the patch below (with the "sleep" removed from .zshrc) and let us
know if it resolves the problem?

If it does, I wonder if we should just queue_signals()/unqueue_signals()
around the entire body of zrefresh(), always?  Or is this the only place
that's important?  (And is it important to protect initmodifier() too?
