Bug ID: 477855 Summary: Plasmashell consumes CPU time doing nothing Classification: Plasma Product: plasmashell Version: 5.27.9 Platform: Other OS: Linux Status: REPORTED Severity: major Priority: NOR Component: Panel Assignee: plasma-b...@kde.org Reporter: stefan.bru...@rwth-aachen.de CC: niccolo.venera...@gmail.com Target Milestone: 1.0 SUMMARY After plasmashell has started, it is consuming CPU time doing apparently nothing. According to strace, it is woken up due to a ~16ms ppoll timeout. This is likely some animation which has not been stopped correctly. The polling stops as soon as the "Status and Notification" popup is opened the first time, afterwards the process is completely idle. STEPS TO REPRODUCE 1. Start plasmashell (as part of the session, or with --restart, does not matter) 2. Attach strace to the main thread 3. Open the popup using the ^ up arrow OBSERVED RESULT Plasmashell consumes CPU time doing nothing, and behaves correctly after opening the popup once. EXPECTED RESULT Plasmashell becomes idle immediately after start, without user intervention.
