Created attachment 166523 [details] CPU usage in htop SUMMARY *** /usr/bin/kwin_x11 --replace uses 20%25% CPU /usr/lib/xorg/Xorg -nolisten tcp -background none -seat seat0 vt2 -auth /run/sddm/xauth_vxVEuW uses 15-20% CPU All the time with just Brave browsed, Telegram, and Slack running. Every 2 minutes or so, keyboard and mouse input display stops being processed for several seconds. Keystrokes are not lost: if you type while the input stops displaying, everything you typed eventually appears. The mouse pointer can move during that period, but clicks are not processed and the pointer shape does not change to e.g. grab or arrow or caret when hovering over elements that would cause it to change normally. This makes the computer mostly unusable. This happens in Wayland and x sessions and did not happen before 6.0.0. *** STEPS TO REPRODUCE 1. Update an up to date KDE Neon User distro to Plasma 6.0.0 using pkcon update. 2. Use the computer. OBSERVED RESULT Two kwin binaries spike the CPU and cause input update lags. EXPECTED RESULT CPU usage does not spike and input does not lag. SOFTWARE/OS VERSIONS Operating System: KDE neon 6.0 KDE Plasma Version: 6.0.0 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.5.0-21-generic (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-10510U CPU @ 1.80GHz Memory: 46.7 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics Manufacturer: LENOVO Product Name: 20RYS0M100 System Version: ThinkPad T490 ADDITIONAL INFORMATION This did not happen before Plasma 6.0.0.
Can you run hotspot please and post a screenshot of the flame graph here?
also is there anything in kwin logs? `journalctl --user-unit plasma-kwin_x11 --boot`
.
I'll add logs in a little bit but wanted to add this note: I've had Google Meet video calls all morning, and the audio stream was completely UNaffected by the CPU spike and input lag. The video stream WAS affected, with the video freezing and not updating for 5-10 seconds every 1-2 minutes, then resuming. This happens on both the internal and external screens.
