zsh sometimes doesn't show stdout
When I have a command that generates a lot into stdout zsh recently (last 6 months AFAIR) stopped showing the output.
e.g.
when I do a:
for i in `seq 2000`; do echo AAA; done
I don't get any output, and even when I press new line (enter) the cursor doesn't move, but the requests are going out.
When I reduce the number in seq:
for i in `seq 20`; do echo AAA; done
I do get output.
When I run both commands in bash I get output in each case.
What happened to zsh? Did it start to buffer the stdout somehow? Or is it seq fault somehow?
zsh version: debian/5.6.2-3
My .zshrc is quite long, but it worked in one version and in another it started behaving so strangely. Is there an option for buffering or something?
UPDATE:
I've narrowed it down to following entry in my zshrc:
case $TERM in
*xterm*|rxvt|(dt|k|E|a)term)
preexec () {
print -Pn "e]2;$1a"
}
;;
screen*)
preexec () {
print -Pn "e"$1e134"
}
;;

linux bash zsh

I have no problems with zsh 5.6.2; please include details about your version (echo $ZSH_PATCHLEVEL) and try without loading your personal config (zsh -f).

@mpy Thanks, I added my version and without my personal config it works. What can be causing such strange behavior?

Unfortunately, also with the code you posted (to change title of terminal / screen to currently running program), I cannot reproduce the behavior you describe. I even went up to 2000000 without problems.
