Bug ID: 440386 Summary: High CPU use of kwin_wayland when video playing in firefox Product: kwin Version: 5.22.4 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: fab...@ritter-vogt.de Target Milestone: --- When using firefox in a wayland session and playing a video on youtube, kwin_wayland takes a constant ~75% CPU (single core) and Firefox is at ~25%. It does not make a difference whether Firefox is running as Wayland or X11 client. This slows applications like plasmashell down massively, to the point of being unusable. This issue does not happen in a X11 session. -- You are receiving this mail because: You are watching all bug changes.
