Package: openssh-client Version: 1:8.9p1-3 If I use ssh -XAf localhost xterm to run a second xterm, then ssh eats up 100% CPU after closing the first xterm. Same happens for xeyes or other XWindow apps. It doesn't have to be localhost, either. "nohup ssh -XAf ..." seems to work, but for Bullseye it works very well without nohup. SHELL is bash 5.1-6 Regards Harri
