Hey, I made another scan through my journal and saw, that kglobalaccel is not the source of the 2 min break. At least for myself I seen the 2min breaks in logs comes from at-spi2-core [1].
At least the analyses of my logs are telling me that the restarting and failure of kglobalaccel is done within 1-2 secs. And your log samples also telling, that the restart is not taking longer than 2secs. Sure the restarting is annoying but it does not seem like the root of the 2min break. 22:13:38 dbus-daemon[5399]: [session uid=1000 pid=5399] Successfully activated service 'org.kde.Shutdown' [... 11 secs later] 22:13:51 systemd[5372]: gpg-agent.service: Consumed 21.189s CPU time. 22:15:21 systemd[5372]: at-spi-dbus-bus.service: State 'stop-sigterm' timed out.
