Yes, that's what __tmux_guard does, it sends the DCS P tmux; followed by SIXEL DCS followed by ST. I got the wrapper code and modified it from iTerm2's imgcat.

I was testing my plots, and when I run the plot from gnuplot, it sometimes renders and sometimes fails. I piped it to a file and to sha1sum, and I'm constantly getting the same sha1sum. However, when I cat the file that I piped the pixel plot with tmux DCS wrapper, that renders every time I cat the file. Could there be a buffering issue with the amount of data going through my shell script/sed?

- Oh it is probably too slow so tmux is aborting the DCS. You can try bumping the timeout in input_start_timer.

Yes, I ran gnuplot and it spat text to the screen, and I cat the plot.sixel.tmux file to render the image too. cat'ing the file seems to work reliably to render, running gnuplot in pipeline does not.
I've gotten the gnuplot to render sometimes and do text garbage the next invocation, back to back just up-arrow/enter and I get different terminal behavior from tmux.
I'm leaning towards some latency in gnuplot generating/piping data through sed vs cat'ing the image from disk to screen makes a difference in control sequence processing.Is that a recompile to adjust the hardcoded timer, or can it be overwritten in a config?
https://github.com/tmux/tmux/blob/master/input.cI put a sleep 0.2 in my __tmux_guard before the DCS P tmux;, and I'm seeing the rendering be more reliable. Thanks for the assistance!
