very high plasmashell/kwin cpu load when using geoclue

[OlafLostViking]

Lately, my laptop (up-to-date plasma/kwin on intel from Arch/Manjaro) started becoming sluggish (and hot...) after some time. Restarting plasmashell helped for some time.

After trying out lots of stuff, I found out that the automatic location identification of redshift using geoclue2 was the culprit. Setting the location manually and disabling geoclue made my desktop usable and nicely reddish again ;-)

Since geoclue was not bubbling to the top in htop, it took a while to come to this solution. Perhaps there is some kind of deadlock inside of redshift when it tries to communicate with geoclue? Just wanted to report that finding, as there are many questions online where people are wondering, why their desktop crawls to an halt.
