Bug#870302: pavucontrol: High CPU usage

[Vincent Lefevre]

Control: found -1 5.0-2
Control: tags -1 upstream
Control: forwarded -1 https://gitlab.freedesktop.org/pulseaudio/pavucontrol/-/issues/73

Deselecting the "Show volume meters" option at the bottom of
the Configuration tab avoids the issue.

But with it being selected, the high CPU usage occurs even in tabs
where no volume meters are shown, such as the Configuration tab
(and in the Playback tab when nothing is played).

The issue is that this activates the fan of my laptop, with probably
battery drain when on battery.
