Entering Coherent view turns all windows panels grey/blank

[Maria@Parallels]

It also happens with parallels 14 or 15 (Testversion), I have a similar same problem.
I was using safari in sidecar and parallels in coherence mode, cursor disappeared, after 1 Minute Mac Catalina shut down, after restart parallels was not working in coherence any more.
I only can see the open windows in Control Center.

Hi, did you reinstall Parallels Tools and check the issue?

I reinstalled Catalina, everything is fine now, thank you
