Created attachment 170726 [details] system monitor showing high cpu usage of kwin_x11 (this is likely reported in the wrong place, please move where it belongs) SUMMARY Since an update a week ago (Discover > update all > reboot), the `kwin_x11` hogs CP. Consequently, the machine becomes hot and the fan is always running high. That CPU usage is usually in the th 20..35% range, even when `kwin_x11` is sleeping. STEPS TO REPRODUCE 1. Update 2. Reboot OBSERVED RESULT As stated above and in screenshot. EXPECTED RESULT `kwin_x11` should burn much less cycles. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20240613 KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.3-1-default (64-bit) Graphics Platform: X11 Processors: 8 × 11th Gen Intel® Core™ i7-1165G7 @ 2.80GHz Memory: 31,1 GiB of RAM Graphics Processor: llvmpipe This may be related to #465424; like there, I use an external HDPI monitor on a laptop.
I cannot reproduce now. Went back to a system snapshot about 2 weeks old, then a summary update (Discover) of all ~1.6k updates, now kwin_x11 stays in the lower 1-digit cpu usage percent. Changing to resolved.
