Bug ID: 440401
Summary: [Wayland] Huge performance drop since 5.22.3
Product: plasmashell
Version: 5.22.3
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-performance
Assignee: plasma-b...@kde.org
Reporter: cblegare....@ntis.ca
Target Milestone: 1.0
SUMMARY
Since the 5.22.3 (also in 5.22.4), overall performance significantly dropped to
the point the system is barely usable.
STEPS TO REPRODUCE
1. Use KDE Neon with Plasma 5.22.2
2. Update to a newer version
3. Observe very slow performances
OBSERVED RESULT
CPU usage and RAM usage look normal, but application are very slow to respond
and keyboard inputs are delayed in any application. Sound in video chat is
distorted because of lag.
EXPECTED RESULT
No major performance change when updating.
