Mac client screen unresponsive after few minutes of idling

Mac client version / Screenconnect version: 20.13 (20.13.1905.7657)

We have an annoying longstanding issue with all of our mac clients connecting to a windows guest machine.

It works fine but after leaving it "idle" for just a few minutes (2-3?) we see a small refresh/hickup and suddenly you cant click anywhere in the guest screen. When we for example shortly switch between View Logon session > back stage and then back to normal view it works again but we have to keep te screen active with user interaction or it will stall/hang again.

We already tried upgrading various times but the problem always remains.
