SUMMARY
My volume sliders freeze up if i'm too quickly dragging them to change volume.
This only happens if i drag them with the mouse, not while changing volume via
keyboard or via the scrollwheel. I've noticed wireplumber cpu usage goes to
100% on one core. if i downgrade wireplumber to 4.17 it gets better but still a
bit janky. Happens on both x11 and Wayland.
I am unsure if this is a kde bug since an earlier version of wireplumber works
better but this issue does not happen on xfce4 at all.
STEPS TO REPRODUCE
1. have wireplumber ver 5.1 running
2. change system volume via any slider, either in the sound applet or in
systemsettings
OBSERVED RESULT
Slider freezes for a while
EXPECTED RESULT
Slider is smooth
