CPU usage on MacOS

Hi community,
I am pretty new with Cryptomator but what surprised me is how much CPU is app taking when idle.
Current setup is 1 vault in iCloud, 6 files, 4MB of size in total. Idle Cryptomator usage is between 3.3 and 4.1%.

Is that normal behaviour? Why there us any usage at all?

Currently testing on multiple machines like:
Macbook pro 15" 2017, Quadcore 2.8GHz i7, 16GB RAM
macOS Catalina 10.15.2

Thank you for your oppinion.

This is a known issue that is somehow caused by the UI rendering. It is now fixed withthe reworked UI of 1.5.0.
