Description of problem: When I execute a command, tmux is prepending <9d>777;preexec<9c> to the output but it looks like whitespace until I attempt to copy it. When I paste into the browser it appears like 777;preexec However, when I paste it into vim it shows up as <9d>777;preexec<9c> Version-Release number of selected component (if applicable): tmux-2.9a-3.fc31.x86_64.rpm How reproducible: Always Steps to Reproduce: 1. Install tmux on Fedora 31 Xfce Spin 2. Run any command ('echo "foo"' is enough to cause the issue) 3. Additional Information: I grabbed the tmux-3.0a-1.fc32.src.rpm from koji and rebuilt locally for fedora-31-x86_64 in mock and installed it, the new version resolved the issue so unless there's any backwards compat breakage, this might just need to be an upgrade for f31.
FWIW this looks related, I'm guessing tmux just handled it themselves also in the 3.0 or 3.0a release. https://github.com/TragicWarrior/libvterm/issues/147
I noticed the following anomaly in non-root screen sessions: [dboth@david ~]$ echo "Hello world" 777;preexecHello world [dboth@david ~]$ The extraneous 777;preexec text is inserted in PS1 by the /etc/profile.d/vte.sh script. Commenting out the last few lines, the “case” statement circumvents the problem. This problem does not appear in root screen sessions or in any non-screen sessions, root or otherwise. I hope this helps.
