I kept seeing garbage like 10;rgb:ff00/ff00/ff0011;rgb:1200/1200/1200 on the input line in tmux after resizing the terminal or attaching to a tmux session (over ssh running on an OpenBSD host). I found that the issue had been reported to tmux, but apparently it's an issue with rxvt-unicode: https://github.com/tmux/tmux/issues/3470 Reproducible: Always Steps to Reproduce: 1. SSH into a system that is running the openbsd-7.4 version of tmux 2. Start tmux 3. Resize the terminal or detach and reattach the tmux session Actual Results: Spurious input like 10;rgb:ff00/ff00/ff0011;rgb:1200/1200/1200 appears. Expected Results: No change on the shell prompt or other input to the program running in tmux The GitHub issue has a link to a patch to rxvt-unicode: https://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/ports/x11/rxvt-unicode/patches/patch-src_command_C?rev=1.6&content-type=text/plain Here's the version of the patch I'm running locally that fixes the issue: OSC commands returning the colour sequence must be terminated by either of ST, ESC \, or BEL. rxvt-unicode tries to use the same type of termination as was in the query but doesn't correctly handle the multiple-char sequence used for 7-bit queries. Force to using ESC \ instead for now.
