I have Hiri running in the background, but it is always using a significant amount of CPU. Following it using top it's typically using 25-30% CPU. Other than checking for new email and events, it shouldn't really be doing anything. Why does it use so much CPU and is there a way to fix that?
My System and settings:
KDE Neon 5.18
Hiri 188.8.131.52 installed via SNAP
2 pane view
