Windows 10 client with guest extensions installed on Parallels 16 on either Catalina or Mojave. Under prior Parallels version(s), accessing those Windows clients with the Microsoft RDP client app worked fine. Now (no manual changes to VM settings) the RDP displays are very scrambled; lagging window updates or wrong colors or multiple copies of a window on the screen at the same time. Pretty much unusable. The VM console display is still fine, and for a VM on the local desktop, that's ok; but for a VM on another Mac, one ends up using VNC to access the other Mac, and then the VM console display there, which is not as good as an RDP client talking directly to the guest Windows OS (which remotes audio as well as video, and handles screen updates better).
