I've installed XRDP on my Debian Linux host for remote access. Everything works fine except for the the guest windows inside WSPro. The colours are all wrong (and weird) and response time is extremely slow when interacting with the guest. It's not a major issue as I can VNC into the guests directly from my desktop and that is extremely quick and stable. The main purpose of XRDP is for managing the VMs via WSPro, which I can do as long as I don't try to interact with the running guest VM. But if there's something that can be done to fix it then of course that would be preferable.
See the attachments for examples of the colour issue.
Update: setting 16 bit colour on the RDP connection resolved the weird colours issue. But the laggy mouse inside the VM is still an issue, but not critical.
