Just to keep track, you can remove my earlier report (https://bugzilla.kernel.org/show_bug.cgi?id=217864 <https://bugzilla.kernel.org/show_bug.cgi?id=217864>) from regzbot.

Hopefully someone else can find the root cause of the problem. My systemd version is: 254.1, and I also use dbus 1.14.10 and dbus-broker 33.r35.g2220a84 which was configured with -D linux-4-17=true. > Do you have test environment with similar configurations so that you can bisect there? > Some other observations: It was very odd to notice that with 6.5.* local h264 video playback with mpv did not work any longer - mpv did not even open the files (it works fine with the older Kernel); the monitor refresh rate was set to 165 Hz (instead of the manually set 120 Hz) and opening of the task bar, Dolphin or attaching files to an E-mail took a lot longer to bring up the dialog than with the older Kernel. Hitting the power button still could successfully turn off the PC though, but clicking on the usual shutdown/reboot Plasma Desktop icons did not seem to work, at least not reliably in every case. > In that case, can you attach mpv output?
