V2.3.* sucks CPU time when "idle"

at least running Logic-2.3.7-master.AppImage and 2.3.8 un Ubuntu 18.04 constantly use way more than one CPU load when doing “nothing” – output from “top” with both 2.3.7 and 2.3.8 running in palallel (2.3.7 connected to Logic Pro 16, 2.3.8 in demo mode for crash debugging only)

output of “top” – the high load average of ~12 is only due to those two Logic 2.* processes!

update:
after typing this, I just found/downloaded 2.3.9 which “covers several important CPU utilization bugs”, and now this looks MUCH better (just did a very quick capture).

@harald.koenig2 Glad to hear the update in 2.3.9 fixed it for you! Seems the case for most users so far who experienced the high CPU usage in previous versions.
