[Pkg-xfce-devel] Bug#876285: xfce4-battery-plugin: stable 10% CPU usage after switching from AC to battery power on X220

[Ivan Krylov]

Left it running for a while (a few days, hibernating and switching
between AC power and battery from time to time) and noticed a stable
increase in the CPU usage:

PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
20   0  474088 139736   6900 R  29,9  0,9 215:47.65 panel-8-battery

I've collected 1,3G of profiling samples using `perf`. `perf report`
considers _gtk_css_selector_tree_match_all from libgtk-3.so.0.2200.11
to have the most overhead.

Here's a magnet link to perf.data, xz-compressed into a 211M file:
