I am running Mac Catalina 10.15.6 and have XQuartz 1.18.4 installed. After running any successful command on XQuartz the follow characters are written to the terminal: 64;1;2;6;9;15;18;21;22c. I also have a custom prompt in my .zshrc file that reads:
export PROMPT='%(?.%F{green}√.%F{red}X)%f %B%F{240}%1~%f%b %# '
This just shows a green check when a command is successful and red x when a command fails. When this is removed the characters do not show in XQuartz. Thus, my question is: how can I preserve the functionality for my regular zsh shell and not have the characters show when running XQuartz?
