STEPS TO REPRODUCE

2. Click on hidden systray icon
3. Click on launcher

OBSERVED RESULT
1. Notice that the panel takes longer time to update itself to show the running and closed apps
2. It takes longer for the blue "line" above the systray icon to come and go
3. It takes longer for the blue "line" above the launcher icon to come and go
EXPECTED RESULT
1. It should reflect the changes faster

ADDITIONAL INFORMATION
Comment 1 David Edmundson 2022-09-14 09:26:04 UTC 
There isn't enough information there to act upon. I have not noticed such issues.

Can you confirm if setting the render loop to basic changes things (kcmshell5 qtquicksettings)

Is CPU spiked? If so can you grab a trace with hotspot.
