Parallels Desktop 15 Pro (Catalina host - Catalina guest) - corrupt dialogs / menus / bars

Dear Parallelers,

as stated i am using a Parallels 15 Desktop 15 Pro on an MBP 16 with Catalina (10.15.3) as host and a Catalina (10.15.3) as guest.

I first recognized problems with the Chrome UI (bars and tabs), which i was able to fix by turning of Chrome´s hardware acceleration.
Unfortunately i discovered similar problems, e.g. in Skype, where several dialogs did not display their elements all or displayed them partially and in a manner only.​

Are there any setting regarding graphics i could alter to get a graphically stable Catalina client?

Thx for any help in advance
Yours Marcus

 

I'm having a similar issue and would love to know if there's a resolution.
