I'm testing out some Ubuntu VM's and found that I'm encountering an interesting issue. When I connect through the web based noVNC option i've seen a couple occurrences of a black screen in some application windows. It appears that the application is still running fine behind the black windows since I can click and get dialog boxes to pop-up.

When i saw this i then setup XRDP and then used MS RDP to connect to this machien and this allows me to see the application as expected. Is there a setting on the VM's that needs to be looked at to help with this issue? Any other thoughts? Maybe a bug?

Started with Ubuntu Server 20.04.1, then installed XFCE gui on top of it. Application of interest is RStudio.

Trying to research a little more on what may be a cause and wonder if the Video -> Model = cirrus has anything to do with what I'm experiencing?
I'm not as versed in this area, but it seems that changes are not retained in this XML config file even if I wanted to try changing it.
