Hi! After the latest update the SDDM starts /usr/bin/startplasma-wayland and then this is started /usr/bin/kwin_wayland_wrapper --xwayland
with the effect of having 2.5 load on a 8 core Ryzen7 and having 70 degrees on CPU!!!

Any idea how can i return the the old, good and efficient Xorg? N.B. that xorg is started anyway: root@hal: ~ # pgrep -a Xorg 4952 /usr/libexec/Xorg -nolisten tcp +iglx -background none -seat seat0 vt2 -auth /run/sddm/xauth_PCdQZB -noreset -displayfd 15
Thank you! Adrian
