Created attachment 170292 [details] perf data captured when the issue happened *** If you're not sure this is actually a bug, instead post about it at https://discuss.kde.org If you're reporting a crash, attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** SUMMARY High CPU usage and lag operation when use for a while. STEPS TO REPRODUCE 1. Open Plasma 2. Use it for a while OBSERVED RESULT You will get lag operation and see high CPU usage in htop. EXPECTED RESULT It will run normally. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.0.90.1 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION I will upload perf data captured when the issue happened
oh no, I forget to set call-graph dwarf I seems no longer lag after I did perf record
I tried to open the perf data, but perf data is not very transferrable across devices. A screenshot from hotspot your side might be more useful. Unfortunately this is not actionable in the current state. Putting in needsinfo.

flamegraph has been uploaded, but perf data is too large to upload.
Thanks for the bug report. I'm sorry we weren't able to get to this yet. There have been many fixes and improvements since this was opened, and this issue may have been fixed. Can you please re-test on your system with Plasma 6.3.4 or later and let us know if you can still reproduce the problem? If you do still see performance issues, can you attach a new screenshot of the flame graph? Thanks!
