[Bug] React Error #185: Input buffer overflow with rapid character input via xdotool

Resolved 💬 5 comments Opened Dec 30, 2025 by KJ7LNW Closed Feb 14, 2026

Bug Description
If I'm typing fast enough into the program, I can get it to crash. This is not pasting, this is high speed character input using the xdotool tools because I dictate most of my commands with my voice. This is version 2.0.76.

The following command reliably reproduces the problem. It sleeps two seconds to give you time to click on the CC window before it starts spamming:

sleep 2; xdotool type "$(perl -e 'print "foo bar " x 1000')" --delay 0
