reassign 981201 xvfb thanks I've submitted a pull request against xvfb-run to achieve this. https://salsa.debian.org/xorg-team/xserver/xorg-server/-/merge_requests/6 Hopefully the X strike force folks will look at it kindly.
FWIW, the way this can be reproduced easily even on amd64 is: 1. in first terminal, run "Xvfb :66" 2. in second terminal, run "DISPLAY=:66 xeyes" 3. in third terminal, run xlsclients in a tight loop: "while :;do DISPLAY=:66 xlsclients || echo FAIL;done" - it will produce a stream of "yourhostname xeyes" 4. then press CTRL+C in the second terminal 5. notice how in the third terminal, xlsclients has failed to connect
