When I right click the first time on any favorite item or any app in kicker menu, the contextual menu is taking long time to appear. See attached video for more info.
The second right click is much faster than the first one.

According to hotspot, on my system we spend almost 900ms loading the Appstream Pool which is loaded on first access.

This issue also affects kickoff.
Comment 6 Patrick Silva 2021-02-24 12:47:28 UTC 
This issue is still reproducible with kickoff and kicker after I restart Plasma
with "plasmashell --replace".

Also reproducible immediately after login.
At least kickoff is also affected on Arch linux.

> Yeah can confirm. :(

It's even reproducible with the new launcher in 5.21.
Comment 10 Nate Graham 2021-03-03 00:36:58 UTC 
Yes, nothing about this changed with the new menu.

This problem happens only the first time (directly after fresh boot) when you right click on any item in app launcher.
Comment 13 Patrick Silva 2021-06-25 15:01:01 UTC 
possibly related: Application Dashboard and krunner take a few
seconds to open for the first time after login on Arch Linux (Plasma 5.22.2) and neon unstable.

This is fixed in the code rewrite for Plasma 5.23!
Comment 15 Alessandro Astone 2021-09-21 07:05:49 UTC 
This is still present in 5.22.90.
Consistently reproducible with the first right-click after login.
Comment 16 Nate Graham 2021-09-21 17:14:03 UTC 
Yeah, I can actually reproduce it :(
Comment 17 Patrick Silva 2022-06-16 02:12:59 UTC 
I'm unable to reproduce with kicker or kickoff after recent updates on neon unstable.

Indeed, neither can I. Must have been fixed with some KWin change in current git master.
Comment 19 Patrick Silva 2022-07-07 11:20:17 UTC 
Unfortunately it's still reproducible on neon unstable with the first right-click after login. But currently the delay does not occur consistently.

kicker: Load appstream pool not on menu construction

Loading the appstream pool has a potential high cost if the cache
is not up to date. When this happens there is noticeable delay
between the right click happening and the menu being shown. Instead
move the cost to when invoking the action.

Comment 25 Tom Strausbaugh 2022-12-08 04:55:46 UTC 
This is happening to me as well. When logged in Right clicking the desktop there is a 5-6 second delay. Subsequent right clicks seem fine. Right clicking between monitors/desktops causes the lag too. I noticed though after a few minutes of the system running it go back the normal with instant right clicks. Thanks.

Great! Thanks Nate.
Comment 28 tsengalb99 2023-01-12 22:54:53 UTC 
I am having the same issue in 5.26.5. What is the recommended course of actual before 5.27 is released? Also, I get the issue after switching to another window and clicking back on the desktop.
Comment 29 Nate Graham 2023-01-13 01:14:34 UTC 
Some options I can think of:

1. Download plasma-workspace source code, patch it with https://invent.kde.org/plasma/plasma-workspace/commit/0b47416af0ac41a705000e53d867406d27774b05 then build it from source for yourself

2. Convince your distro to backport https://invent.kde.org/plasma/plasma-workspace/commit/0b47416af0ac41a705000e53d867406d27774b05 to their plasma-workspace package and ship it out as an update

3. Wait for Plasma 5.27
