Bug ID: 434218
Summary: Using the Mute hotkey repeatedly while having the
plasma-pa applet open makes Plasma shell slow down
Product: plasma-pa
Version: 5.21.2
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: applet
Assignee: now...@gmail.com
Reporter: ben.r.x...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: ---
SUMMARY
If you open the plasma-pa widget and press the Mute key on your keyboard
repeatedly, Plasma Shell starts to slow down. It first manifests as a slight
delay before devices are muted/unmuted. If you continue to do it, eventually
Plasma shell slows to a crawl every time you press the Mute key and takes
longer and longer to recover. Eventually, pressing the Mute key makes the
entire Plasma desktop inoperable for minutes at a time.
STEPS TO REPRODUCE
1. Click on the Volume icon in the panel to open up the plasma-pa widget
2. Press the mute key repeatedly and observe the devices being muted and
unmuted.
3. Eventually you'll notice that the devices seem slower to react to the mute
key and that the Plasma desktop is slow to darn near inoperable when in this
state.
OBSERVED RESULT
Repeated mute key presses with plasma-pa open slows down Plasma
EXPECTED RESULT
Mute key should not slow down Plasma

ADDITIONAL INFORMATION
I am also using Pipewire instead of Pulseaudio. Not sure if that has anything
to do with this bug.
