Video that shows a delayed popup and the same popup appearing immediately after
the first delay.
SUMMARY
In KDE Plasma 5.17 (Neon User, but it also happened on 5.16 and on Manjaro)
some popups, such as confirmations when moving files to trash or any
informational popup related to Plasma itself, shows up with a huge delay. I
figured out a few things that may help figure out the bug.
Basically, the delay starts presenting itself when I change the default output
device. I have a motherboard with an integrated soundcard as it is normal, but
I prefer to output through my monitor via the DisplayPort or HDMI cable. If I
go to ~/.config/pulse and delete everything then restart pulseaudio, popups are
instantaneous again, but as soon as I set HDMI\DP as default output, they
become laggy again.
Also, the delay only happens for popups that have a sound associated with it.
If I remove the sound, the popups appear immediately.
Finally, after a delayed popup, all subsequent ones are instantaneous. But
after a while, the same popup will be laggy again.
