Bug ID: 416044 Summary: Increased Energy Consumption of kwin wayland with active Screen Lock Product: kwin Version: 5.17.5 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: m...@rainer-finke.de Target Milestone: --- I measured today the energy consumption on a AMD APU and experienced an increased energy consumption of kwin during an active screen lock. In my case the system consumed idle on the desktop 11 Watt (Wayland), but as soon as the lock screen kicks in, the system consumes continuously 13,5 Watt. Even if the screen is turned off, the energy consumption is with 12,5 Watt still higher than on an idle desktop. If I open htop with ssh and look at the CPU% of kwin_wayland, it is on the desktop more or less idle (mostly at 0%), but with the lock screen it is at 5% and with the monitor turned off at 2%. STEPS TO REPRODUCE 1. Open Plasma (Wayland) 2. Wait until the screen is locked OBSERVED RESULT - Increased energy consumption EXPECTED RESULT - Same or less energy consumption Operating System: Arch Linux KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.65.0 Qt Version: 5.14.0 Kernel Version: 5.4.8-arch1-1 OS Type: 64-bit CPU: AMD Ryzen 3 2200G -- You are receiving this mail because: You are watching all bug changes.
