Package: procps Version: 2:4.0.2-3 Severity: normal The version of top in bookworm seems to have changed the processing of the <space> keybinding for :Refresh-Display, and you can see it immediately drawing the screen *twice* while registering the current `top` process as something taking 100% of the CPU.
The former behaviour was to just trigger the timer right now, and calculate the resource usage and refresh. This was useful. The new behaviour is to calculate resource usage, refresh, wait 0 seconds, calculate resource usage (funnily enough, the only thing to take CPU since 0 seconds ago was top itself), and refresh again. This is not useful, because it hides the behaviour of the rest of the system, which had only a tiny chance of being scheduled in those timeslices where top was recalulating if they were using anything less than 100% of a core(s). Tested on a vanilla system just case I had done something funky in .toprc. manpage doesn't seem to deal with reverting to previous behaviour, and doesn't mention any change in how <Space> or :Refresh-Display may have been changed. -- System Information: Debian Release: 12.8 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable'), (5, 'testing'), (2, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.10.11+bpo-amd64 (SMP w/16 CPU threads; PREEMPT) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages procps depends on: ii init-system-helpers 1.65.2 ii libc6 2.36-9+deb12u9 ii libncursesw6 6.4-4 ii libproc2-0 2:4.0.2-3 ii libtinfo6 6.4-4 Versions of packages procps recommends: ii psmisc 23.6-1 procps suggests no packages. -- no debconf information
