Created attachment 185519 [details] errors from journalctl SUMMARY I've been very confused by htop readings of 10% or more cpu utilization even when idle for kwin_wayland process.... Tried many stuff but in the end it seems like bringing up the taskbar from auto hide mode lets cpu go back to 1% or 2% usage. Attached journalctl logs which mention some other errors as well. STEPS TO REPRODUCE 1. Start something for example floorp 2. Ensure cpu goes above 10% or something 3. Close it after some time OBSERVED RESULT CPU usage doesn't go below 10% and sometimes more unless taskbar is activated or kwin_wayland --replace is run. CPU usage drops immediately as well EXPECTED RESULT CPU usage should be lower when idle SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.2 Kernel Version: 6.17.0-4-cachyos (64-bit) Graphics Platform: Wayland Processors: 12 × 12th Gen Intel® Core™ i5-12450H Memory: 16 GiB of RAM (15.3 GiB usable) Graphics Processor 1: Intel® Graphics Graphics Processor 2: NVIDIA GeForce RTX 4060 Laptop GPU ADDITIONAL INFORMATION I have been using cachyos repo packages installed while pacstrapping (its a recent re-installation). Installed mesa-tkg-git and also tried Intel Xe driver both high cpu usage issue and the other errors still persist.
