This can be verified by running the commands

printf %4083s

which works, versus

printf %4084s

which crashes and sometimes freezes, when run from a Shin input inside a GTK application on GNOME. When a crash occurs, stdout contains the message

Error reading events from display: Broken pipe

This does not happen on KDE or Sway, even on the same base system and with the same GTK applications.

My guess is that the number 4083 is 4096 minus the size of the DBus header or something. There appears to be a GNOME-specific limit at work here. The other DEs can handle much larger outputs without any problems.
