I tried to change the resolution within the machine using Solus' displays resolution tool to no avail. In the view tab of Virtual Box under the Virtual screen menu all of the resolution settings are grayed out and thus unavailable. Older versions of Vitrual Box allowed users to scroll the screen inside the VM's window. Version 6.04, the latest version does not have this feature, so I am still stuck.
The only other options I can try that will resolve the issue is to use VMWare Player or VMWare Workstation Pro. It's that or rolling back to an older version of Virtual Box. I would like to get it working in Virtual Box 6.0.4 if possible.
