That actually confirms even more that it's cause by the waylandtasksmodel, as that is by default not accessible when using valgrind due to kwin access controls. To disable those, kwin_wayland needs to be started with KWIN_WAYLAND_NO_PERMISSION_CHECKS=1. You can add that to /etc/environment or cat <<EOF >/run/user/1000/systemd/user/plasma-kwin_wayland.service.d/override.conf [Service] Environment=KWIN_WAYLAND_NO_PERMISSION_CHECKS=1 EOF and log out and in again. -- You are receiving this mail because: You are watching all bug changes.
