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. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.22 KDE Plasma Version: 5.22.3 KDE Frameworks Version: 5.84.0 Qt Version: 5.15.3 Kernel Version: 5.8.0-63-generic (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-8665U CPU @ 1.90GHz Memory: 15.3 Gio of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 ADDITIONAL INFORMATION Switching back to X and I don't feel any performance drop. I am not sure what additional information I should provide, but will happily get anything asked.
Hmm, cannot reproduce.
Maybe it has something to do with my multi monitor setup? Also, how could you reproduce this, I mean how can you reliably pick a specific version of Plasma?
>Sound in video chat is distorted because of lag. Kwin can't cause that.
I don't know about KWin, I created the issue in `plasmashell` originally. What info could I provide to help?
