Wayland
Product: plasmashell
Version: 5.24.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

Demonstration of Kickoff being slow
SUMMARY
After waking from sleep (not hibernate) on Wayland, pressing the Super key to
open Kickoff will cause it to appear but be unresponsive for a few seconds. Any
input that is typed into Kickoff won't appear immediately but instead after it
becomes responsive again.
Also, switching virtual desktops causes the panel to freeze (which is why this
is not marked as a Kickoff bug exclusively) so this is possibly related to
https://bugs.kde.org/show_bug.cgi?id=451631
After a certain amount of time woken from sleep Kickoff and the panel return to
normal.
I'm not sure if this bug occurs EVERY time after suspend but it has happened
enough that it's noticeable. Has happened to me on both openSUSE Tumbleweed on
an AMD GPU and Fedora 35 on an Intel GPU.
AFAIK does not happen on X11.
STEPS TO REPRODUCE
1. Start a Plasma Wayland session
2. Suspend the computer
3. Wake the computer
4. Attempt to use Kickoff or switch virtual desktops
OBSERVED RESULT
Kickoff and the panel are slow and unresponsive
EXPECTED RESULT
Kickoff and the panel respond as normal
