After disabling and re-enabling different things to try to find the problem reason, It seems that this problem is related to the Panel, because when setting the Panel-Visibility option to Auto_Hide, and the Panel is in hidden mode, CPU usage back to normal, and when the Panel is visible, the problem is starting again; Also when the Panel-Visibilty option seted to Always-Visible and the applicattion(Konsole) window be FullScreen, It has no effect on the problem. Also, this problem is probably(I'm not entirely sure) related to the changes between August 9 and 15 because after updated Plasma on August 10(openSUSE Krypton repo 22-08-09) I did not notice to this problem but after updated Plasma on August 14(openSUSE Krypton repo 22-08-14) I noticed to the problem. I noticed this as well and it's just been fixed as of today, with https://invent.kde.org/frameworks/plasma-framework/-/commit/3ac9fc30c766c3ed57f0d4f19fb2a7d046b46118. |
Last Sunday, after updating Plasma to the last git-master(openSUSE Krypton repo 22-08-14), I noticed unusual and continuous CPU(And probably also GPU) usage by Plasmashell and Kwin_wayland processes in the Wayland session, And in the X11 session, in addition to them, the Xorg-bin process is also involved, So that even when just running Top through Konsole, in Wayland session, CPU usage of Plasmashell and Kwin_wayland processes is about 7-8%, and in X11 session, CPU usage of Plasmashell and Kwin_x11 and Xorg-bin processes is about 10-12%, And it also seems that something constantly and without reason render/draw/repaint ing in the background, because seems that "kworker/u9:1+i915_flip" process is also involved. Also, I had not seen this problem before the last update.
