Bug ID: 414785 Summary: Notifications cause system lag Product: plasmashell Version: 5.17.3 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Notifications Assignee: k...@privat.broulik.de Reporter: k...@jbev.net CC: plasma-b...@kde.org Target Milestone: 1.0 SUMMARY Whenever a notification appears, my system starts lagging, including a sudden break in audio playback. Also, when I am copying files or downloading something in Chrome (with Plasma integration add-on), desktop effects show noticeable delay while the operation is running. For example, switching virtual desktops feels very sluggish, whereas without a progress notification going, it's fast and snappy. This happens even when the copy/download status notification popup isn't visible. As long as there is a hidden notification tracking the progress of an operation, the system is laggy. STEPS TO REPRODUCE 1. Play some music 2. Trigger a notification Alternatively: 1. Download a large file 2. Switch between desktops OBSERVED RESULT Audio stutter and effect delays. EXPECTED RESULT None of that.
