Created attachment 124194 [details] 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. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Neon 5.17 KDE Plasma Version: 5.17.3 KDE Frameworks Version: 5.64.0 Qt Version: 5.13.2 ADDITIONAL INFORMATION Video of the issue is attached.

(In reply to Mark Smith from comment #2) > (In reply to Patrick Silva from comment #1) > > bug 416527 seems duplicate/related > > How did you solve it? my pulseaudio was not working and it was causing my problem despite I always mute the notification sounds on my system. Now pulse audio is working again here and I can't confirm your issue on my system even if system sounds are not muted. I use camberra for notification sounds. I'm not mistaken, phonon is problematic and can cause your issue. https://wiki.archlinux.org/index.php/Libcanberra
I don't know much about this kind of stuff but I am pretty sure libcanberra is installed and enabled on my system and it is the default on KDE Neon User Edition. I think the issue only presents itself when you change the default output device. I changed it from the built in soundcard (which I also disabled but I don't think it matters) to the HDMI output on my Nvidia Geforce GTX1060 so that I can use the speakers connected to my monitor. If I have the HDMI output (see screenshot) selected, I get the lag unless I remove the sound associated with the event.

After messing up my system beyond repair, I reinstalled. I used the latest 5.20 iso and then updated to 5.20.1. As usual my audio output is as follows GPU -> HDMI -> Monitor -> Speakers With sounds associated to events, from just the popping sound that happens when changing the volume using the keyboard to the bling sound that plays to confirm deleting a file, there is a massive delay like in my first video. And this makes me really sad :( Operating System: KDE neon 5.20 KDE Plasma Version: 5.20.1 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.0 Kernel Version: 5.4.0-52-generic OS Type: 64-bit Processors: 4 × Intel® Core™ i5-3570K CPU @ 3.40GHz Memory: 7,7 GiB of RAM Graphics Processor: GeForce GTX 1060 6GB/PCIe/SSE2
